Comment(by dimpase):
Replying to [comment:7 dimpase]:
> Many of these graphs can be trivially generated in GAP using its package
Grape (a part of the optional gap_packages spkg) and
> a library of primitive groups (a part of optional databases_gap spkg).
actually, Grape isn't even needed (I mentioned it for illustrative
purposes): to construct the Sage graph,
all you need is the following:
{{{
sage: edges=gap('Orbit(PrimitiveGroup(27,12),[1,2],OnSets)')
sage: schlaefli=Graph([[int(x[1])-1,int(x[2])-1] for x in edges])
}}}
PS. To get e.g. Hall-Janko graph, use {{{PrimitiveGroup(100,1)}}}...
