On 2 nonsplit extension groups associated with HS and HS:2
(Turkish JournalPark, 2014)The group HS:2 is the full automorphism group of the Higman--Sims group HS. The groups 24.S6 and 25.S6 are maximal subgroups of HS and HS:2, respectively. The group 24.S6 is of order 11520 and 25.S6 is of order 23040 and ... -
Some irreducible 2–modular codes invariant under the symplectic group S₆(2)
(2014)We examine all non-trivial binary codes and designs obtained from the 2-modular primitive permutation representations of degrees up to 135 of the simple projective special symplectic group S6(2). The submodule lattice of ...
