Dear Forum

Few days a go I have obtained GAP from internet and I have printed the
manual GAP. I find in the references of the manual GAP the next paper:

Gordon F. Royle. The transitive groups of degree twelve,
J. Symbolic Computation, pages 255-268,1987.

wich I suppose that is incrporated to GAP.
In this paper we can find that Mr. Royle gives a imprimitive group of order
252900 wich contain the prime divisor 281(page 265). As you can see this
is imposible because this group is contained in S_12.
I think that the order of this group must be 259200.
?are there another involuntary mistakes in the paper of Mr. Royle

I like know if the information contained in the paper of Mr.Royle are the
same that GAP.

?is there anyone in the Forum that can tell me how to obtain from GAP a
list of imprimitive groups of degree twelve.

Please mail replies to me rather than list GAP.

thank in advance for you attention
