On the Movement of a Permutation Group
If \((G,\Omega)\) is a permutation group, then the movement \(\text{move}(G)\) is the supremum of \(\{|\Gamma^g\setminus\Gamma|:\Gamma\subseteq\Omega,\;g\in G\}\). If \(G\) has no fixed points, \(n:=|\Omega|\), and \(\text{move}(G)=m\) is finite, then \(n\leq 5m-2\), by a result of \textit{C. E. Praeger} [J. Algebra 144, No.

Trivial source bimodule rings for blocks and p-permutation equivalences [PDF]
We associate with any p-block of a finite group a Grothendieck ring of certain p-permutation bimodules. We extend the notion of p-permutation equivalences introduced by Boltje and Xu [4] to source algebras of p-blocks of finite groups.

3-Homogeneous Groups and Block-Transitive 7–(v, k, 3) Designs
The classification of a block-transitive designs is an important subject on algebraic combinatorics. With the aid of MATLAB software, using the classification theorem of 3-homogeneous permutation groups, we look at the classification problem of block ...

The Fixity of Permutation Groups
By definition, the fixity of a finite permutation group \(G\) is the maximal number of fixed points of a non-identity element of \(G\); so if \(f\) denotes the fixity of \(G\) and \(n\) the degree of \(G\) then \(n-f\) is the minimal degree of \(G\). The authors prove some general theorems on transitive permutation groups \(G\) with given fixity \(f>0\)

ON THE SPECTRUM OF DERANGEMENT GRAPHS OF ORDER A PRODUCT OF THREE PRIMES [PDF]
A permutation with no fixed points is called a derangement. The subset $mathcal{D}$ of a permutation group is derangement if all elements of $mathcal{D}$ are derangement.

The Birkhoff theorem for unitary matrices of prime-power dimension [PDF]
The unitary Birkhoff theorem states that any unitary matrix with all row sums and all column sums equal unity can be decomposed as a weighted sum of permutation matrices, such that both the sum of the weights and the sum of the squared moduli of the ...

Novel Criteria for Deterministic Remote State Preparation via the Entangled Six-Qubit State
In this paper, our concern is to design some criteria for deterministic remote state preparation for preparing an arbitrary three-particle state via a genuinely entangled six-qubit state.

Permutation Polytopes of Cyclic Groups [PDF]
We investigate the combinatorics and geometry of permutation polytopes associated to cyclic permutation groups, i.e., the convex hulls of cyclic groups of permutation matrices.
