We propose a new family of constraints which combine together lexicographical ordering
constraints for symmetry breaking with other common global constraints. We give a general
purpose propagator for this family of constraints, and show how to improve its complexity by
exploiting properties of the included global constraints.

We propose a new family of constraints which combine together lexicographical ordering constraints for symmetry breaking with other common global constraints.
