    This thesis studies symmetry properties of error-correcting codes, which have digital, and mathematical, applications. A code consists of strings of a fixed length in some alphabet.

    A code is 2-neighbour-transitive if it satisfies particular symmetry properties. New infinite families of 2-neighbour-transitive codes are exhibited, certain subclasses classified, and a full characterisation given in the binary case.

    A code is s-elusive if it exhibits less symmetry than the set of strings at distance s from it. Elusive codes are shown to be related to certain designs, with infinite families of examples provided.

    Finally, possible extensions of the main results are discussed.
