We present an interface between the ECLiPSe constraint logic programming system and the GAP computational abstract algebra system. The interface provides a method for efficiently dealing with large numbers of symmetries of constraint satisfaction problems for minimal programming effort. We also report an implementation of SBDS using the GAP-ECLiPSe interface which is capable of handling many more symmetries than previous implementations and provides improved search performance for symmetric constraint satisfaction problems.
