1. Permutations and Combinations: In mathematics, the notion of permutation relates to the act of permuting (rearranging) objects or values. Question 1: How many ways can you re-arrange the following bunch of numbers?. [100%] 2023-03-01 [Mathematics]
2. Permutations by cycle type: The conjugacy classes of the symmetric group Sn are defined by the permutations' cycle types. The cycle types correspond to the integer partitions of n. [86%] 2024-01-02 [Cycle structure of permutations]
3. Permutations of Boolean functions: Analogous to hard and soft properties of Boolean functions, there are also hard and soft permutations. A permutation is hard, when the domain is the infinite set of all Boolean functions. [86%] 2025-01-23 [Studies of Boolean functions]
4. Permutations and partitions in the OEIS: Permutations of a finite set are often sorted lexicographically, but reverse colexicographical order gives an infinite order of finite permutations. (In this order the inversion vector of the n-th permutation interpreted as a factorial number is n.) The finite ... [70%] 2023-04-14 [Permutations] [Set partition]...
5. Paradiddle permutations: < School of Music and Dance | Drums This article is about the different permutations or variations of a drum rudiment called the Paradiddle. The paradiddle is one of the 40 Essential Drum Rudiments. [100%] 2023-12-13 [Drums]
6. Arrays of permutations: These are some examples of similar permutations ordered in arrays. Each permutation is represented by its: For the last permutation in each array the corresponding permutation matrix is also shown. [81%] 2023-12-13 [Permutations] [Inversion (discrete mathematics)]...
7. Primitive group of permutations: primitive permutation group A permutation group $ ( G, M) $ that preserves only the trivial equivalences on the set $ M $( i.e. equality and amorphous equivalence). (Mathematics) [70%] 2023-12-13
8. Hopf algebra of permutations: In algebra, the Malvenuto–Poirier–Reutenauer Hopf algebra of permutations or MPR Hopf algebra is a Hopf algebra with a basis of all elements of all the finite symmetric groups Sn, and is a non-commutative analogue of the Hopf ... [70%] 2023-12-12 [Hopf algebras]
9. Bit permutations by cycle type: The following table shows the bit permutations corresponding to the 5!=120 permutations of 5 elements ordered by cycle type. The violet numbers represent partitions by index numbers of  A194602 (compare this table). [63%] 2024-01-03 [Walsh permutation] [Cycle structure of permutations]...
10. Order 4 magic squares; Walsh permutations: There are 24*9=216 Walsh permutations that correspond to magic squares of order 4. They have these 9 compression vectors and all their permutations: The following table shows the compression vectors in the RevCoLex order of the permutations.

11. Skew and direct sums of permutations: In combinatorics, the skew sum and direct sum of permutations are two operations to combine shorter permutations into longer ones. Given a permutation π of length m and the permutation σ of length n, the skew sum of π and σ is the permutation ... [57%] 2023-02-18 [Permutations]
