Combinatorics 2026-01-01 v5

Abstract

In this paper various Steiner systems S(2,k,v)S(2,k,v) for k=6k = 6 are collected and enumerated for specific constructions. In particular, two earlier unknown types of 11-rotational designs are found for the groups SL(2,5)SL(2,5) and ((Z3×Z3)Z3)×Z5((\mathbb Z_3 \times \mathbb Z_3) \rtimes \mathbb Z_3) \times \mathbb Z_5. Also new Steiner systems S(2,6,96),S(2,6,106),S(2,6,111)S(2,6,96), S(2,6,106), S(2,6,111) are listed.
