Cyclically permutable representations of cyclic codes

open access: yesDiscrete Applied Mathematics, 2008
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

open access: yesForum of Mathematics, Sigma, 2021
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.

Join Products K2,3 + Cn

open access: yesMathematics, 2020
The crossing number cr ( G ) of a graph G is the minimum number of edge crossings over all drawings of G in the plane. The main goal of the paper is to state the crossing number of the join product K 2 , 3 + C n for the complete ...

On knot separability of hypergraphs and its application towards infectious disease management

open access: yesAIMS Mathematics, 2023
The article deals with some theoretical aspects of hypergraph connectivity from the knot view. The strength of knots is defined and investigates some of their properties.

Generating a random cyclic permutation [PDF]

open access: yesBIT, 1988
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

open access: yesIACR Transactions on Symmetric Cryptology, 2023
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]

open access: yesJournal of Algebraic Systems, 2021
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]

open access: yes, 1981
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

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2004
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

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 1993
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.
