Vanstone's construction applied to Bhaskar Rao designs

We show how Vanstone's construction, given in his paper "A note on a construction for BIBD's", Utilitas Mathematica, 7(1975), 321-322, can be applied to symmetric GBRD(v, k, λ; │G│). │G│ odd, can be used to obtain GBRD(v, (v2), (k2), λ, (λ2); G) and hence many families of BIBD.
