HX-hypergroups associated with the direct products of some ${bf Z}/n {bf Z}$
One studies the $HX$-hypergroups, corresponding to the Chinese hypergroups associated with the direct products of some ${bf Z}/n {bf Z},$ calculating their fuzzy grades.
متن کاملDerangements on the n-cube
Chen, W.Y.C. and R.P. Stanley, Derangements on the n-cube, Discrete Mathematics 115 (1993) 65-15. Let Q. be the n-dimensional cube represented by a graph whose vertices are sequences of O’s and l’s of length n, where two vertices are adjacent if and only if they differ only at one position. A k-dimensional subcube or a k-face of Q. is a subgraph of Q. spanned by all the vertices u1 u2 u, with c...
متن کاملAutomorphisms of the Cube n
Consider a hypergraph H n where the vertices are points of the d-dimensional combinatorial cube n and the edges are all sets of n points such that they are in one line. We study the structure of the group of automorphisms of H n, i.e., permutations of points of n d preserving the edges. In this paper we provide a complete characterization. Moreover, we consider the Colored Cube Isomorphism prob...

متن کاملTransmitting in the n-Dimensional Cube
Alon, N., Transmitting in the n-dimensional cube, Discrete Applied Mathematics 37/38 (1992) 9-1 I. Motivated by a certain communication problem we show that for any integer n and for any sequence (a,,...,ak) of k = [n/21 binary vectors of length n, there is a binary vector z of length n whose Hamming distance from a, is strictly bigger than k-i for all 1 5 i 5 k. The n-dimensional cube is the g...
