This is a past event.

Visitor Bernardo Rodrigues of the University of KwaZulu-Natal will be speaking on "Linear codes with complementary duals from regular graphs invariant under finite groups."


We determine all linear codes of length 50 over Fp (p a prime) which admit the projective special unitary group U3(5) as an automorphism group. By group representation theory means we prove that these can all be realized as submodules of the permutation module FΩ where Ω corresponds to the vertex set of the Hoffman-Singleton graph.
