....generated symmetry group. For example, to generate SN it is sucient to provide one permutation that switches exactly two elements, and another permutation that cycles each element by one position. The following GAP session illustrates this for the symmetric group on 7 points: gap p2 : PermList([2,3,4,5,6,7,1]) gap g : Group(p1,p2) gap Size(g) 5040 As a further example we generated the symmetry group of a square from one rotational symmetry and one ip symmetry in Section 2. The greatest number of generators needed is O(log 2 (N ) and this bound is reached only for a small class of ....
....within the backtrack search for a solution. It should be possible to implement the subsidiary search in GAP, leaving ECL to deal with the resulting (pruned) search tree. It would also be interesting to explore the application of our work to the satis ability problem, in which Crawford et al. [6] successfully applied group theoretic techniques. The second area is the extension of our approach to more practical CSP problems. In particular the areas of symmetry in model checking [4] and vehicle routing and scheduling [2] Acknowledgements. The St Andrews authors are assisted by EPSRC ....
