Title: There are 1239 Steiner triple systems STS(31) of 2-rank 27
Authors: Osuna, OP
Issue Date: 2006
Abstract: A computer search over the words of weight 3 in the code of blocks of a classical Steiner triple system (STS) on 31 points is carried out to classify all STS 31 whose incidence matrix has 2-rank equal to 27, one more than the possible minimum of 26. There is a total of 1239 nonisomorphic STS 31 of 2-rank 27.
