The binary linear codes generated by incidence matrices of the 80 Steiner triple systems on 15 points (STS( )) are studied. The 80 codes of length 35 spanned by incidence vectors of the points are all non-isomorphic. In contrast, a pair of codes of length 15 generated by blocks are isomorphic if and

We are interested in the sizes of cliques that are to be found in any arbitrary spanning graph of a Steiner triple system S S. In this paper we investigate spanning graphs of projective Steiner triple systems, proving, not surprisingly, that for any positive integer k and any sufยฎciently large proje
## Abstract The codewords at distance three from a particular codeword of a perfect binary oneโerrorโcorrecting code (of length 2^m^โ1) form a Steiner triple system. It is a longstanding open problem whether every Steiner triple system of order 2^m^โ1 occurs in a perfect code. It turns out that thi
