Maximal subgroups of odd index in $\mathrm{PSL}(3,q)$
A pretty complete and accessible description of this can be found in a survey article of Oliver King. In addition to the link, here's the citation info:
King, Oliver H., The subgroup structure of fi …

Simplicial set of permutations
I think something equivalent (or at least closely related) to this has been studied in the combinatorics literature.
A CW complex of course has a poset of faces. In this case, this poset is obtain …

Computing the inner automorphism group of a finite Lie algebra
I'm interested in writing GAP code to compute the inner automorphism group of a finite Lie algebra. (I'd like to be able to group conjugate subalgebras together.) I've had trouble finding good refer …

Computing the inner automorphism group of a finite Lie algebra
I accepted @Paul Levy's answer, but meanwhile I want to add some further extended comments, references, and experimental data. Perhaps this will be useful to someone else at some point.
As Paul Levy …

Proofs of some combinatorial identities
It's not the formally published literature, but unless I'm mistaken, the last of your three identities appears in Stanley's list of bijective proof problems (dated 2009) as number 194. He says there …

Visualizing large posets
I'm seeing this question very late, but have two possibly useful suggestions for drawing posets:
My favorite way to automatically draw large graphs with unknown structure is GraphViz. See

Constructing a simplicial set homology-equivalent to a given CW complex
(the following is an expanded version of what was previously a comment)
I don't see why you think homotopy equivalence is an unreasonable requirement. Indeed, Theorem 2C.5 of Hatcher's Algebraic Top …

Reference request on Leray numbers
For question 1, the earliest reference I know is:
Ralf Fröberg, On Stanley-Reisner rings, Topics in algebra, Part 2 (Warsaw, 1988), Banach Center Publ., vol. 26, PWN, Warsaw, 1990, pp. 57–70.
