Small FDIRC designs

Bhaskar Rao designs over small groups

We show that for each of the groups S3, D4, Q4, Z4 x Z2 and D6 the necessary conditions are sufficient for the existence of a generalized Bhaskar Rao design. That is, we show that: (i) a GBRD (v, 3, λ; S3) exists if and only if λ ≡ O (mod 6 ) and λv(v 1) ≡ O(mod 24); (ii) if G is one of the groups D4, Q4, and Z4 x Z2, a GBRD (v, 3, λ; G) exists if and only if λ ≡ O(mod 8) and λv(v 1) ≡ O(mod 6)...

Small non-isomorphic repeated measurements designs

Over the last few years a number of authors have investigated the structure of optimal measurements designs. Various constructions for such designs have been given. In this paper we consider the construction of non-isomorphic optimal repeated measurements designs when t=2 and

The intersection problem for small G-designs

A G-design of order n is a pair (P, B) where P is the vertex set of the complete graph Kn and B is an edge-disjoint decomposition of Kn into isomorphic copies of the simple graph G. Following terminology, we call these copies "blocks". Given a particular the intersection problem asks for which k is it possible to find two (P, Bl) and (P, B 2) of order n, with IBI n B21 = k, that is, with k comm...
