and Kac-Moody groups:
The Conway groups, $Co_{1}, Co_{2}, Co_{3}$, are three of the sporadic finite simple groups. A fourth group, $Co_0$, is the group of automorphisms of the Leech lattice with respect to addition and inner product. This latter group is not simple, but $Co_1$ is the quotient group of $Co_0$ by its center of order 2. The other two simple Conway groups are subgroups of $Co_1$.
The simple Conway groups are three of the seven members of the ‘second generation’ of the Happy Family of 20 simple subquotients of the Monster group.
The Conway group $Co_{0}$ is the group of automorphisms of a super VOA of the unique chiral N=1 super vertex operator algebra of central charge $c = 12$ without fields of conformal weight $1/2$
