Behold Combinatorial Computation, the Missing Face of the Coins of Permutations and Combinations of Specified Set (N) and Selection (R)
Statement of the Problem: In Mathematics (combinatorics in particular) discrete objects in sets are separated into two categories: one of similar objects and the other of dissimilar objects in case of deployment in multiplication only or multiplication accompanied by arrangement operations. Multiplication only applies to sets of similar objects, while multiplication accompanied by arrangement applies to sets of dissimilar objects. Both operations accomplish increase in quantity by number for their respective sets. Furthermore, multiplication accompanied by arrangement concerning sets of dissimilar objects is guided by one of two conditions; one where order of placement of the objects is important and the other the order of placement of objects is unnecessary. The arrangement of the set where order is important is called permutation and that where order is unimportant is called combination. Nevertheless, both permutation and combination go by specification of set (n) and selection (r), more or less in correspondence with the specification of multiplicand and multiplier terms applicable to the multiplication of objects that are similar, for proper performance in the determination of increase of quantity by number. In the case of determination of increase of quantity by number in combinatorics embracing permutations and combinations of specified set (n) and selection (r) calculation and computation operations come into play. Calculation offers the number of arrangements (factorials) using peculiar formulary, while computation using view mixing techniques presents the entire membership of the calculated factorials, individually. Calculation and computation are the two opposite faces of the coin of permutation and combination at work in the determination of increase of quantity by number via arrangement of set of dissimilar objects in combinatorics.
Methodology and Theoretical Orientation: This is a maiden presentation of the methodologies for computing permutations and combinations of specified set (n) and selection (r) involving two distinct schemes: one of Square Kinematics View Mixing for 4 from 4 i.e., _{4}P_{4} for permutations only and the other, Solid State View Mixing for r from n i.e., _{n}P_{r} for permutations and i.e., _{n}C_{r} for combinations. The theoretical orientation of both methods is view mixing in two opposite directions along the axis of each array in the case of permutations and in one direction only in the case of combinations.
Findings: Square Kinematics View Mixing Scheme was used in producing 24 quadruplets for 4 from 4 permutation factorial i.e., _{4}P_{4} = 4! = 4x3x2x1 = 24 quadruplets. Also, Solid State View Mixing Scheme was used in computing 10 triplet combinations for 3 from 5 combinations.
Conclusion and Significance: Square Kinematics View Mixing Scheme and SolidState View Mixing Scheme for computing permutations and combinations of specified set (n) and selection (r) represent breakthroughs in computational combinatorics in Mathematics in the 21^{st} century.
Recommendations: The two techniques are recommended for wide publicity for relief to the world of computational combinatorics in Mathematics.

INTRODUCTION
Permutations and Combinations are twin themes in Combinatorics in Mathematics. Each of them has two faces like a coin; one face featuring Calculation and the other Computation. Permutations go by two specifications; one of fullset selection e.g., _{n}P_{n, }and other of subset selection e.g., _{n}P_{r, }where (n) is the set and (r) is the selection for r < n. Combinations, on the other hand, go by one specification only which is subset selection e.g., _{n}C_{r }for r < n. The calculation face of Combinations of specified set (n) and
subset selection
(r) concerning prediction of the number of factorial (arrangement) has been operational for long by reason of the formula, established long ago in Mathematics Literature [14]. But the computation face of combinations of specified set (n) and selection (r) concerned with the presentation of the calculated factorials has remained blank till now for lack of technique(s) or scheme(s) for computing the calculated factorials. Likewise, the computation face of the coin of permutations of specified set (n) and selection (r) has remained blank till now for lack of technique(s) or scheme(s) for computing the calculated factorials whether for full set selection or subset selection. But here comes Solid State View Mixing Scheme, a technique capable of computing the calculated factorials for all specified set (n) and selection (r) for both permutations and combinations alike.
This is a breakthrough in computational combinatorics in Mathematics! Thanks to Advances in Computational Combinatorics by this author.
Solid State View Mixing Scheme has two distinct input mixing procedures namely PlaceSkipped Input (PSI) and DigitSkipped Input (DSI) to work with three types of mixerhead viz: square mixerhead, polygonal mixerhead, and circular mixerhead. Given a common input set (n) and selection (r), the three different mixerheads using each of the two input mixing procedures at a time produce unique output sequences of the factorials of either permutations or combinations, wherein the input set is remarkably proliferated and diversified [57].
DEFINITIONS
Combinations: The number of ways in which (r) objects can be chosen from a set of (n) dissimilar objects without regard to the order of selection is called the number of combinations of (n) objects taken (r) at a time.
Permutations: The number of possible distinct arrangements of (r) objects chosen from a set of (n) dissimilar objects with regard to order of selection is called the number of permutations of (n) objects taken (r) at a time.
Isodigitation: Digitisms (multidigital numbers) bearing repetition of one or more digits.
Deisodigitation: The removal of digitisms bearing repetitions of one or more digits.

Description
 Computation of factorials of permutations of specified set (4) and selection (4) PSI.
Fullest selection permutation computation
By fullest selection it is meant that the selection is equal to the set. We have come to one of the points at issue in the unfolding of the SolidState Mixing Scheme as a technique for the computation of permutations. We intend to demonstrate the performance of the Scheme with fullset selection of 4 from 4, input mixing algorithms of PSI (Placeskipped input) for square digital mixer polygon.
Square Mixerhead: Square mixerhead is employed for the full set selection 4 from 4 (Figure 1).

DISCUSSION
Solid State View Mixing Scheme is a versatile technique that has emerged recently from Numeration science literature in the making to keep the computation face of the coins of both permutations of fullset selection and subject selection operational likewise the computation face combinations of subset selection are made operational; by inchoate Solid State View Mixing Scheme. The number of factorials for any specified set (n) and selection (r) of permutations and combinations as calculated by formulary can also be computed henceforth by Solid State View Mixing Scheme.
Solid State Mixing Scheme is a great arrangement device for computation of permutations and combinations of specified set (n) and selection (r), being fully equipped with accessories such as (i) interserial numbering with or without circumferencing. (ii) view mixing with or without substitution, and (iii) displacement mixing with a variety of options as used in charts 2,3 and 4 in the text. Solid State View Mixing Scheme and Square Kinematics being arrangement devices in Numeration Science amply justify the designation of Numeration Science as Science of number and arrangement.
