Comment (by dimpase):
Do you really need the whole Golay code for this? This graph has vertex-
transitive automorphism group, Mathieu(24), acting on certain 12-subsets.
Or you can use `AtlasGroup`:
{{{
sage: g=libgap.AtlasGroup("M24",libgap.NrMovedPoints,1288)
sage: G=Graph()
sage: G.add_edges(libgap.Orbit(g,[1,2],libgap.OnSets))
sage: G.is_strongly_regular(parameters=True)
(1288, 495, 206, 180)
}}}
