A minimal faithful permutation representation — 2 generators on 59 points:
(1,2,3,4,5)(11,12,13,14,15,16,17,18,19,20,21,22,23,24,25,26,27,28,29,30,31,32,33,34,35,36,37,38,39,40,41,42,43,44,45,46,47,48,49,50,51,52,53,54,55,56,57,58,59);(6,7,8,9,10)1225 conjugacy classes. The character table is too large to display.
