This is the software described in the technical report “The GF2Matrices Classes: A Programming Package for Mathematical Research.” Over the past few years I have been engaged in an intense study of GF(2) matrices, especially of dimensions 2, 3, 4, and 5. The software I used for this study was mostly a bunch of ad-hoc subroutines scattered over numerous projects. This package consolidates all of this software into a system of classes. This software can be used to reproduce any of my results. This package is distributed without any warranty of any kind.
