A minimal faithful permutation representation — 4 generators on 25 points:
(1,2)(3,4,5,6,7,8,9);(10,11,13,16,14,17,20,23)(12,15,19,22,18,21,24,25);(12,18)(15,21)(19,24)(22,25);(1,2)(10,12)(11,15)(13,19)(14,18)(16,22)(17,21)(20,24)(23,25)280 conjugacy classes. The character table is too large to display.
