[GAP Forum] Automorphism group of a graph

[Dmitrii (Dima) Pasechnik]

Dear Fatemah,
GAP has a package GRAPE (you might need to install it separately)
which is capable to deal with graphs and their automorphism groups directly.
IMHO there is no interface between GAP and MAGMA available, so you'd
need to write/read files to pass data between two systems.
(Well, in fact Sage has such an interface built in, but that's another story).

HTH,
Dmitrii
