comment Generating random finite groups
It's not clear to me that the procedure described above wouldn't favor certain isomorphism classes. The original question wanted an equal chance at each isomorphism class of groups of order $n$.

comment Generating random finite groups
Indeed, GAP even knows the count of these groups with NumberSmallGroups (but it won't let you get at the groups themselves via the SmallGroups library).

answered Is there a (satisfying) proof that cellular cohomology is isomorphic to simplicial cohomology that doesn't use relative cohomlogy?

comment Making spheres shellable
Is the difference with the Adiprasito and Benedetti theorem in the nature of the allowed subdivisions? They only look at derived subdivisions.

comment Generalization of a theorem of Øystein Ore in group theory
There's also Roland Schmidt's nice book "Subgroup lattices of groups", which goes into a bit more depth on most of these and many related topics.

comment quasiprimitive non-solvable groups
John, that link looks wustl.edu specific. Try ams.org/mathscinet-getitem?mr=2661653 instead. (And no mathscinet access is required for that link.)

comment Factor subset of finite group
@Geoff Robinson: Yes, sounds like a good place to look for a possible counterexample.

comment Characterising extendable automorphisms
The groupprops wiki has a couple of articles regarding this, e.g. groupprops.subwiki.org/wiki/Extensible_automorphisms_problem . While I found these to be rather incomplete, they give a start in finding some references.
