Let G be a finite elementary abelian p-group. Given a 2-cocycle β£ of G over the field of complex numbers, we show how to construct an irreducible projective representation of G with 2-cocycle in the cohomology class of β£. Let S be a 2 ## Ε½ . subgroup of G of index dividing p . Then we also count
