Computing second cohomology of finite groups with trivial coefficients
Pages: 163 – 168
The paper describes a simple procedure for computing the second cohomology $H^2(G,A)$ of a finitely presented finite group $G$ with coefficients in a finitely presented finite abelian group $A$. An accompanying text-file contains a Magma implementation of the procedure.
