A minimal faithful permutation representation — 2 generators on 36 points:
(1,2,3,4)(5,6,7,8,9)(10,11,14)(12,18,22)(13,17,23)(15,24,20)(16,27,21)(19,29,32)(25,35,36)(26,34,31)(28,33,30);(10,12,19,13,20,30,21,31,36)(11,15,25,17,26,29,16,18,28)(14,22,32,23,24,33,27,34,35)340 conjugacy classes. The character table is too large to display.
