Abstract
The theory of Q-reducible space groups is applied to determine those line groups in two dimensions which are isomorphic to factor groups of Q-reducible two-dimensional space groups. The concept of Q reducibility is extended to subperiodic groups, and the strip groups isomorphic to factor groups of the subperiodic layer groups are determined.
