AbstractA plane of order n having an abelian transitive group of (P, l) transitivities yields generalized Hadamard matrices with entries from a group of order g for any g|n. Generalized Hadamard matrices of degree 12 are given having entries from groups of order 4 and 3, respectively. Unfortunately these do not yield a plane of order 12 having a (P, l) transitivity
