A length n group code over a group G is a subgroup of Gn under component-wise group operation. Two-level group codes over the class of generalized quaternion groups, Q(2m), m⩾3, are constructed using a binary code and ...

This paper deals with Euclidean space codes obtained from two-level group codes of length n over a generalized quaternion group Q m, m⩾3, with 2m elements, with generators x and y, given by the presentation ...
