An analogue of the Pless symmetry codes
Gabriele Nebe, Darwin Villar · 2013
Dedicated to the memory of Professor Stefan Dodunekov Abstract. A series of monomial representations of SL2(p) is used to construct a new series of self-dual ternary codes of length 2(p + 1) for all primes p ≡ 5 (mod 8). In particular we find a new extremal self-dual ternary code of length 60. 1
