Dear Forum, Akos Seress, in Bull. London Math. Soc. 29 (1997), 697-704, listed all the (finitely many) primitive groups which have no regular orbit on the power set of their domain. He listed them by GAP number and ATLAS name.
Sad to say, the GAP numbering seems to have changed since then. For example, Akos thought PrimitiveGroup(16,19) is 2^4.A_7, whereas GAP now thinks this group is 2^4.A_5. I have two questions: 1. Does anyone have a list correlating the old and new numbers? I think that, from the ATLAS names, I can recover what he meant, but it would be nice to have a check. 2. Is there any way that we can draw the group-theory community's attention to this, perhaps with an updated list? Peter. _______________________________________________ Forum mailing list Forum@mail.gap-system.org http://mail.gap-system.org/mailman/listinfo/forum
