Ronald Solomon he wrote, and is continuing to write, a series on the
classification program for finite simple groups, a program in which the three of them were major participants. Nine volumes of this series have been published so far. He discovered a
sporadic group which
Charles Sims constructed and called the
Lyons group ''Ly''.
