In this paper we calculate the mod two cohomology of the double cover of the Mathieu group M . The starting point is the calculation by Adem, Maginnis and 12 Milgram of the mod two cohomology of M . We use a hypercohomology spectral 12 sequence to determine a differential in the Lyndon-Hochschild-Se

We give a closed formula for the cohomology groups of the standard integer lattice in the simply-connected Heisenberg Lie group of dimension 2 n q 1, n g Z q . We also provide a recursion relation involving n for these cohomology groups.

We define a group theoretical invariant, denoted by s G , as a solution of a certain set covering problem and show that it is closely related to chl(G), the cohomology length of a p-group G. By studying s G we improve the known upper bounds for the cohomology length of a p-group and determine chl(G)
