Abstract
In this paper an approach to generate multi-dimensionally consistent -component systems is proposed. The approach starts from scalar multi-dimensionally consistent quadrilateral systems and makes use of the cyclic group. The obtained -component systems inherit integrable features such as B\"acklund transformations and Lax pairs, and exhibit interesting aspects, such as nonlocal reductions. Higher order single component lattice equations (on larger stencils) and multi-component discrete Painlev\'e equations can also be derived in the context, and the approach extends to -component generalizations of higher dimensional lattice equations.
