Realizing a monoid as $\mathrm{End}(G)$ for some graph $G$
Actually, their theorem states this under some cardinality constraints: gdz.sub.unigoettingen.de/…

Are loops allowed?

Powers of finite simple groups
The automorphism groups of finite simple groups are well known. So, we have to calculate the (nonreduced) Euler function $\phi_n(G)$ (ie. the number of generating ntuples). In Section 1.1, Collins describes a technique of such calculations that allowed Hall (in 1936) to calculate, e.g., $\phi_2(A_5)=19\cdot 120$ (ie. $h_2(A_5)=19$).

Normal Covering of a Finite Group
This Corollary 5.5 follows immediately from the theorem of Brodie, Chamberlain and Kapp, PAMS 1988, see Nick Gill's answer: mathoverflow.net/a/185604/24165 .

Is the equational theory of commutative vN regular rings decidable?
Thomas, every finitely generated associative commutative ring is residually finite. (For free rings (= polynomial rings), this is almost obvious.)
