Cyclically permutable representations of cyclic codes
A cyclically permutable code is a binary block code of length \(n\) such that each codeword has \(n\) distinct cyclic shifts and such that no codeword can be obtained by one or more cyclic shifts of another codeword. Cyclically permutable codes have been studied for several applications involving synchronization, code-division multiple access (CDMA ...

Skew characters and cyclic sieving
In 2010, Rhoades proved that promotion on rectangular standard Young tableaux, together with the associated fake-degree polynomial, provides an instance of the cyclic sieving phenomenon.

Generating a random cyclic permutation [PDF]
We prove correct an algorithm that, given \(n>0\), stores in array b[0..n- 1] a random cyclic permutation of the integers in 0..n-1, with each cyclic permutation having equal probability of being stored in b. The algorithm was developed by Sattolo; our contribution is to present a more convincing proof using standard program-proving methods.

Chosen-Key Secure Even-Mansour Cipher from a Single Permutation
At EUROCRYPT 2015, Cogliati and Seurin proved that the 4-round Iterated Even-Mansour (IEM) cipher with Independent random Permutations and no key schedule EMIP4(k, u) = k⊕p4 ( k⊕p3 ( k⊕p2 (k⊕p1 (k⊕u)))) is sequentially indifferentiable from an ideal ...

4-CYCLE FREE APM LDPC CODES WITH AN EXPLICIT CONSTRUCTION [PDF]
Recently, a class of low-density parity-check codes based on affine permutation matrices, called APM-LDPC codes, have been considered which have some advantages than quasi-cyclic (QC) LDPC codes in terms of minimum-distance, cycle distribution, and error-

Graphical cyclic permutation groups [PDF]
A permutation group H acting on a set X is said to be graphical if there is a graph G such that Γ(G), the automorphism group of G, is identical to H. Characterisation of graphical permutation groups seems to be difficult. Kagno and Chao have shown that the group generated by a single m-cycle is not graphical.

On the class of square Petrie matrices induced by cyclic permutations
Let n≥2 be an integer and let P={1,2,…,n,n+1}. Let Zp denote the finite field {0,1,2,…,p−1}, where p≥2 is a prime. Then every map σ on P determines a real n×n Petrie matrix Aσ which is known to contain information on the dynamical properties such as ...

Congruences involving generalized Frobenius partitions
The goal of this paper is to discuss congruences involving the function cϕm¯(n), which denotes the number of generalized Frobenius partitions of n with m colors whose order is m under cyclic permutation of the m colors.
