comment Why are there only a finite number of sporadic simple groups?
@Joseph : John is referring to Claude Chevalley's article in the Tohoku Journal : Sur certains groupes simples, Tohoku Math. J. (2) Volume 7, Number 1-2 (1955), pp14-66. You can find it on a library or Project Euclid.

comment A Question about p-primary Group
@Arturo : You seem to think that the original wording of the question should stay and that it is better to have the clarification in the answer. Am I correct?

answered If set is closed under some operation, what does that tell us about the structure of the groupoid?

comment What structure is this?
In your description, r(x) and r(x,y) do not depend on x, but only on the coefficients of f,g,h. Is it a typo or do you really mean that r(x) and r(x,y) are constants and not power series?
