Twisted projective spaces and linear completions of some partial Steiner triple systemsMa{\l}gorzata Pra\.zmowskaInstitute of Mathematics, University of Bia{\l}ystok, ul. Akademicka 2, 15267 Bia{\l}ystok, Poland, email: malgpraz@math.uwb.edu.plAbstract: A class of Steiner triple systems is characterized. Each one is obtained as a linear completion of some $\konftyp(15,4,20,3)$ multiveblen configurations and it contains some Fano planes. Keywords: Desargues configuration, Veblen configuration, partial Steiner triple system, graph, combinatorial Grassmannian Classification (MSC2000): 51E14, 51E30 Full text of the article:
