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);(5,6,9,10)(7,8,11,12)(15,19)(17,20);(6,10)(8,12)(13,14,16,18)(15,17,19,20);(5,7,9,11)(6,8,10,12)(13,15)(14,17)(16,19)(18,20);(5,8)(6,11)(7,10)(9,12)1100 conjugacy classes. The character table is too large to display.
