I will, for the sake of completion, seek other simple maximal groups that might be in common and list them here, after realizing I had forgotten about isomorphisms which could also be simple (but not finite of Lie type or alternating), of which there shouldn't be that many. This is all in an effort to bring clarity to the structure of the sporadic groups, which readers might find interesting to read here.

The following terms in the set, however are of Lie type, without exception.
