Recycling an earlier answer to this question:

"The transitive groups of degree up to eleven" by G. Butler and J. McKay,
in Communications in Algebra, vol. 11, 1983, pages 863--911.

(quoting from the readme file of Michel Olivier's galp directory,
ftp://megrez.math.u-bordeaux.fr/pub/galois/ .  However, galp uses a
somewhat different convention for identifying the groups it finds in
degrees 8 through 11.  The actual PARI code is in src/modules/galois.c,
and the state machines in there together with the files in galdata.tgz
determine the mapping.  I should hope that the numbering used by the
code is the same as that in Butler&McKay, but I'm separated from my
copy of the paper by several miles at the minute, and therefore cannot
check this right now.)

Hope this helps,
Gerhard
