For each orbit O_i we give a canonical representative vertex v_i : (denominator | coordinates) ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ The orbits are ordered first by decreasing incidence Icd_i, then by decreasing adjacency Adj_i and then by increasing orbitsize |O_i| ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ -------------- canonical representatives -------------------------- i denominator | coordinates 1 1 | 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 2 3 | 2 2 2 2 0 0 2 2 2 2 2 2 2 2 2 2 2 2 2 2 0 3 3 | 2 2 2 2 0 2 2 2 2 2 0 2 2 2 2 2 2 2 2 2 2 4 3 | 2 2 2 2 2 0 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 5 3 | 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 6 4 | 1 2 3 1 2 1 1 2 2 1 2 1 1 2 3 2 3 2 1 2 1 7 5 | 4 2 2 2 2 4 4 2 2 2 2 4 2 2 2 4 2 2 4 2 4 8 3 | 1 1 1 1 1 1 2 2 1 1 1 2 1 1 1 1 1 1 2 2 2 9 7 | 2 4 6 4 2 4 2 4 2 4 2 2 4 2 2 2 4 4 2 2 2 10 5 | 3 2 3 3 1 1 1 2 2 2 2 3 3 3 3 4 4 2 2 4 2 11 3 | 1 1 1 1 1 1 2 2 1 1 1 2 1 1 1 2 1 1 2 2 2 12 6 | 1 2 4 2 2 2 1 3 3 3 3 2 2 2 4 2 2 2 4 4 4 13 3 | 2 2 1 1 1 2 2 1 1 1 1 2 1 1 1 2 1 1 2 1 2 -------------------------------------------------------------------
