✦ Synopsis


We define a class of hypercubic (shape n d ) arrays that in a certain sense are d-dimensional analogs of permutation matrices with our motivation from algebraic geometry. Various characterizations of permutation arrays are proved, an efficient generation algorithm is given, and enumerative questions are discussed although not settled. There is a partial order on the permutation arrays, specializing to the Bruhat order on S n when d equals 2, and specializing to the lattice of partitions of a d-set when n equals 2.

## Abstract A __covering array__ __CA(N;t,k,v)__ is an __N × k__ array such that every __N × t__ sub‐array contains all __t__‐tuples from __v__ symbols __at least__ once, where __t__ is the __strength__ of the array. Covering arrays are used to generate software test suites to cover all __t__‐sets

We study a decomposition of Fl n d-1 , where Fl n denotes the flag manifold over n . The strata are defined by the dimensions of intersections of one space from each flag, so for d equal to 2 this is the usual Bruhat cell decomposition. The strata are indexed by "permutation arrays," which are d-dim

## Abstract Motivated by symmetric association schemes (which are known to approximate generously unitransitive group actions), we formulate combinatorial approximations to transitive extensions of generously unitransitive permutation groups. Specifically, the notions of compatible and coherent par
