library package for graph algorithms, is available on our ftp server

The following is an extract from the README.

-----------------------------------------------------------------------------
    GRAPE (GRaph Algorithms using PErmutation groups),
    Version 2.1, L.H.Soicher@qmw.ac.uk, 12 July 1993.

Changes from previous versions of GRAPE other than new functions and new
function parameters:
(1) Nauty Version 1.7 is now used. Note that canonical labellings could
be different from those produced by nauty 1.4, which was used in
previous versions of GRAPE.
(2) EnumColadj now returns an intersection matrix for the trivial
orbital graph, in addition to the intersection matrices for the
other orbital graphs.
(3) MakeIntransitiveGroupGenerators now called
IntransitiveGroupGenerators.
(4) VertexName now returns a copy (of the vertex name).

GRAPE is provided "as is", with no warranty whatsoever. Please read the
copyright notice in the file COPYING.

    Please send comments on GRAPE, bug reports, etc. to
    L.H.Soicher@qmw.ac.uk.
