Abstract

A group G is said to be capable if it is isomorphic to the central factor group H/Z(H) for some group H. Let G be a nonabelian group of order p 2 q for distinct primes p and q. In this paper, we compute the nonabelian tensor square of the group G. It is also shown that G is capable if and only if either Z(G) = 1 or p < q and \({G^{\rm ab}=\mathbb{Z}_{p}\times\mathbb{Z}_{p}}\) .
