MeatAxe

The MeatAxe - Computing with Modular Representations. The MeatAxe is a set of programs for working with matrices over finite fields. Its primary purpose is the calculation of modular character tables, although it can be used for other purposes, such as investigating subgroup structure, module structure etc. Indeed, there is a set of programs (see The Lattice Programs) to compute automatically the submodule lattice of a given module. Each of the programs is self-contained, reading its input from files, and writing its output to files. To make the MeatAxe usable, therefore, it is necessary to write operating system commands to run the various programs. This documentation is primarily for the programs, and further documentation is necessary for the various implementations in differing operating environments. The primitive objects are of two types: matrices and permutations. Permutation objects can be handled, but not as smoothly as you might expect. For example, it is hoped that programs such as split (zsp) and multiply (zmu) will be able to work with mixed types, but at present ZSP is restricted to matrices only, and ZMU can multiply a matrix by a permutation, but not vice versa.
