comment Is every finite group a group of “symmetries”?
@Andrew: I am also sure I have seen a proof that every finite group is a group of automorphisms of a Riemann surface, actually in the context of the Inverse Galois Problem, but the only reference for something quite close that I could find now is: L. Greenberg, Conformal transformations of Riemann surfaces. Amer. J. Math. 82 1960 749–760.

comment Examples of theorems misapplied to non-mathematical contexts
Perhaps it was my being ignorant of algebraic topology as a kid, but splitting my sandwich with my brother did not seem to be fair!

comment Never appeared forthcoming papers
I recalled Robert Thomason citing the various preprints of his paper "Algebraic K-theory and etale cohomology" as "to disappear" We are all glad that the paper finally appeared in Ann. Sci. Ecole Norm. Sup. (1985).

comment Mittag-Leffler condition: what's the origin of its name?
Thanks Yemon. I followed your suggestion and took a look at Runde's (Appendix A) and the "abstract" Bourbaki's M-L version for a sequence of complete metric spaces and continuous funcions $f_n:X_n\rightarrow X_{n-1}$ with dense image. It looks that this can be further abstracted to the "algebraic" M-L. I'll do the details later on to see if this is the case. By the way, Runde quotes Bourbaki's "General Topology" volume. I don't have access to that one right now but I'll check it tomorrow. Thanks again.
