[GAP Forum] a GAP-readable table of the primitive finite subgroups of GL(n, C), for n small?

[pjc at mcs.st-and.ac.uk]

It may be worse than you thought. I just got this from Martin Roeteller:

|Dear Peter,
|
|I was wrong in three ways: first of all it was not about the
|classification of crystallographic groups, it was about the
|finite subgroups of SU(n). And the dimension was not as
|large as n=20, it was as small as n=3 (!!). And the
|original classification was not due to Kneser, as I
|thought, but was due to Blichfeldt.
|
|The paper is Ludl, "Comments on the classification of the
|finite subgroups of SU(3)", J Phys A Math Theory 44:255204,
|2011. Also on the arxiv at http://arxiv.org/abs/1101.2308
|and http://arxiv.org/abs/1310.3746. Apparently he found
|missing subgroups, the smallest one being a split extension
|of order 162.
|
|Best,
|Martin
