Existence results for pentagonal geometries
Anthony D. Forbes, Terry S. Griggs, Klara Stokes
New results on pentagonal geometries PENT(k,r) with block sizes k = 3 or k = 4 are given. In particular we completely determine the existence spectra for PENT(3,r) systems with the…
Designs for graphs with six vertices and ten edges -- II
Anthony D. Forbes, Terry S. Griggs
The design spectrum has been determined for ten of the 15 graphs with six vertices and ten edges. In this paper we solve the design spectrum problem for the remaining five graphs w…
On the upper embedding of Steiner triple systems and Latin squares
Terry S. Griggs, Thomas A. McCourt, Jozef Siran
It is proved that for any prescribed orientation of the triples of either a Steiner triple system or a Latin square of odd order, there exists an embedding in an orientable surface…
On the upper embedding of symmetric configurations with block size 3
Grahame Erskine, Terry Griggs, Jozef Širáň
We consider the problem of embedding a symmetric configuration with block size 3 in an orientable surface in such a way that the blocks of the configuration form triangular faces a…
