Automorphism groups and isometries for cyclic orbit codes

H Gluesing-Luerssen, H Lehmann - arXiv preprint arXiv:2101.09548, 2021 - arxiv.org
We study orbit codes in the field extension ${\mathbb F} _ {q^ n} $. First we show that the
automorphism group of a cyclic orbit code is contained in the normalizer of the Singer …

Minimal logarithmic signatures for finite groups of Lie type

N Singhi, N Singhi, S Magliveras - Designs, Codes and Cryptography, 2010 - Springer
A logarithmic signature (LS) for a finite group G is an ordered tuple α= A 1, A 2,..., A n of
subsets A i of G, such that every element g ∈ G can be expressed uniquely as a product g …
