## Abstract Given a basis ${\cal B} = \{f\_1,\ldots, f\_k\}$ for 2βcocycles $f:G \times G \rightarrow \{\pm 1\}$ over a group __G__ of order $\vert G\vert=4t$, we describe a nonlinear system of 4__t__β1 equations and __k__ indeterminates $x\_i$ over ${\cal Z}\_2, 1\leq i \leq k$, whose solutions de
