Third Homology of some Sporadic Finite Groups

Theo Johnson-Freyd, David Treumann

We compute the integral third homology of most of the sporadic finite simple groups and of their central extensions.

$H^{4} (Co_{0}; Z) = Z /24$

Theo Johnson-Freyd, David Treumann

We show that the fourth integral cohomology of Conway's group $Co_{0}$ is a cyclic group of order $24$ , generated by the first fractional Pontryagin class of the $24$ -dimens…
