A minimal faithful permutation representation — 6 generators on 31 points:
(1,2)(21,22,23,24,25,26,27,28,29,30,31);(3,4);(5,6)(7,11)(8,12)(9,10)(14,15)(18,19);(6,10)(8,11)(13,14,17,15)(16,19,20,18);(5,7,9,12)(6,11,10,8)(13,15,17,14)(16,19,20,18);(5,8,9,11)(6,12,10,7)(13,16,17,20)(14,18,15,19)1100 conjugacy classes. The character table is too large to display.
