The 2-rotational Steiner triple systems of order 25
Chee, Y.M. and G.F. Royle, The 2rotational Steiner triple systems of order 25, Discrete Mathematics 97 (1991) 93-100. In this paper, we enumerate the 2-rotational Steiner triple systems of order 25. There are exactly 140 pairwise non-isomorphic such designs. All these designs have full automorphism groups of order 12. We also investigate the existence of subsystems and quadrilaterals in these d...
متن کاملThe Steiner triple systems of order 19
Using an orderly algorithm, the Steiner triple systems of order 19 are classified; there are 11,084,874,829 pairwise nonisomorphic such designs. For each design, the order of its automorphism group and the number of Pasch configurations it contains are recorded; 2,591 of the designs are anti-Pasch. There are three main parts of the classification: constructing an initial set of blocks, the seed...
متن کاملA Catalogue of the Steiner Triple Systems of Order 19
A method for compressing Steiner triple systems is presented. This method has been used to compress the 11,084,874,829 Steiner triple systems of order 19 into approximately 39 gigabytes of memory. The compressed data can be obtained by contacting the authors.
متن کاملNon - Orientable Biembeddings of Steiner Triple Systems of Order 15
It is shown that each possible pair of the 80 isomorphism classes of Steiner triple systems of order 15 may be realized as the colour classes of a face 2-colourable triangulation of the complete graph in a non-orientable surface. This supports the conjecture that every pair of STS(n)s, n ≥ 9, can be biembedded in a non-orientable surface.
متن کاملBi-Embeddings of Steiner Triple Systems of Order 15
It was shown by Gerhard Ringel that one of the three non-isomorphic Steiner triple systems of order 15 having an automorphism of order 5 may be biembedded as the faces of a face 2-colourable triangular embedding of K15 in a suitable orientable surface. Ringel’s bi-embedding was obtained from an appropriate current graph. In a recent paper, the present authors showed that a second STS(15) of thi...
