A minimal faithful permutation representation — 5 generators on 31 points:
(1,2,3,4)(21,22,23,24,25,26,27,28,29,30,31);(5,6,8,12,9,11,15,18)(7,10,14,17,13,16,19,20);(5,7)(6,10)(8,14)(9,13)(11,16)(12,17)(15,19)(18,20);(7,13)(10,16)(14,19)(17,20);(6,11)(10,16)(12,18)(17,20)1496 conjugacy classes. The character table is too large to display.
