Cyclic colliding permutations

open access: yesElectronic Notes in Discrete Mathematics, 2013
We study lower and upper bounds for the maximum size of a set of pairwise cyclic colliding permutations.

Cyclic permutations for qudits in d dimensions [PDF]

open access: yesScientific Reports, 2019
AbstractOne of the main challenges in quantum technologies is the ability to control individual quantum systems. This task becomes increasingly difficult as the dimension of the system grows. Here we propose a general setup for cyclic permutations Xd in d dimensions, a major primitive for constructing arbitrary qudit gates.

Descents of $\lambda$-unimodal cyclic permutations [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2014
We prove an identity conjectured by Adin and Roichman involving the descent set of $\lambda$-unimodal cyclic permutations. These permutations appear in the character formulas for certain representations of the symmetric group and these formulas are ...

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.

The q-ary image of some qm-ary cyclic codes: permutation group and soft-decision decoding [PDF]

open access: yes, 2002
Using a particular construction of generator matrices of the q-ary image of qm-ary cyclic codes, it is proved that some of these codes are invariant under the action of particular permutation groups.

Vincular pattern avoidance on cyclic permutations

open access: yesEnumerative Combinatorics and Applications, 2021
Pattern avoidance for permutations has been extensively studied, and has been generalized to vincular patterns, where certain elements can be required to be adjacent. In addition, cyclic permutations, i.e., permutations written in a circle rather than a line, have been frequently studied, including in the context of pattern avoidance.

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 the symmetry of good nonlinear codes [PDF]

open access: yes, 1970
It is shown that there are arbitrarily long "good" (in the sense of Gilbert) binary block codes that are preserved under very large permutation groups. This result contrasts sharply with the properties of linear codes: it is conjectured that long cyclic ...

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 ...
