✦ Synopsis


In this paper, a new family of relative difference sets with parameters Γ°m; n; k; lÞ ΒΌ ððq 7 Γ€ 1Þ=Γ°q Γ€ 1Þ; 4Γ°q Γ€ 1Þ; q 6 ; q 5 =4Þ is constructed where q is a 2-power. The construction is based on the technique used in [2]. By a similar method, we also construct some new circulant weighing matrices of order q dΓ€1 where q is a 2-power, d is odd and d55: # 2002 Elsevier Science (USA)

## Abstract We constrain the structure of difference sets with classical parameters in abelian groups. These include the classical Singer 7 and Gordon et al. 4 constructions and also more recent constructions due to Helleseth et al. 5, 6 arising from the study of sequences with ideal autocorrelatio

This paper contains a discussion of cocyclic Hadamard matrices, their associated relative difference sets, and regular group actions. Nearly all central extensions of the elementary abelian 2-groups by Z 2 are shown to act regularly on the associated group divisible design of the Sylvester Hadamard
