The maximal overgroups of noncyclic Sylow subgroups of the sporadic finite simple groups are determined. Moreover a geometric structure is associated to this collection of overgroups, which is useful in the study of sporadic groups.
Moufang loops of small order
by Chein, Orin
fromMemoirs of the American Mathematical Society
In this paper, all nonassociative Moufang loops of order [less-than or equal to symbol] 63 are found, and their properties are investigated. Each of these loops is solvable, satisfies Lagrange's Theorem, has Sylow subloops, and is isomorphic to all of its loop isotopes. All of t…
"For a finite group G of Lie type and a prime p, we compare the automorphism groups of the fusion and linking systems of G at p with the automorphism group of G itself. When p is the defining characteristic of G, they are all isomorphic, with a very short list of exceptions. Whe…
"The notion of a fusion system was first defined and explored by Puig, in the context of modular representation theory. Later, Broto, Levi, and Oliver extended the theory and used it as a tool in homotopy theory. We seek to build a local theory of fusion systems, analogous to th…
