comment Cubic Cayley (undirected) graphs
@verret, thanks for the correction. I've been sloppy and will correct shortly. In any case, the real point of my answer is that the OP should read your work, so I'm glad you also showed up to answer :-)

Correct me if I'm wrong but it looks like this question is a repost of a question that has been closed - mathoverflow.net/questions/178510/…

comment Special linear groups contained in symplectic groups
Yes, that is a more direct way of proving the result. I had forgotten (if I ever knew) that the symplectic Singer cycle would have smaller order in this case than the Singer cycle for $SL$.

comment Special linear groups contained in symplectic groups
@GeoffRobinson, I think you mean the book by Kleidman & Liebeck and the papers by Kleidman(!) I have e-copies of these, so the OP can email if s/he wants a copy. For low-rank groups the new book by Bray, Holt and Roney-Dougal would be very useful.

comment Duration and critical groups order in sandpile models and chip firing games
Do you mean if there is NO vertex which can fire, then the game is over? Also, could you include a definition of the "critical group"? Nice question by the way, +1.

comment orthogonal group in characteristic 2
The subgroup structure of the finite classical groups by Kleidman and Liebeck. I have an e-copy and will send it to you if you want (my e-mail is on my user page).
