A minimal faithful permutation representation — 7 generators on 28 points:
(5,6,7,8)(9,10)(11,12)(21,22,24,25)(23,26,27,28);(6,8)(10,12)(14,17)(18,20)(22,25)(23,27);(6,8)(10,12)(15,19)(18,20);(13,14)(15,18)(16,17)(19,20)(21,22)(23,26)(24,25)(27,28);(3,4);(1,2)(3,4);(5,6)(7,8)(9,10)(11,12)(13,15)(14,18)(16,19)(17,20)(21,23,24,27)(22,26,25,28)392 conjugacy classes. The character table is too large to display.
Past the SmallGroups library coverage — no SmallGroups id. Construct it from a minimal faithful permutation representation:
gap> G := Group((5,6,7,8)(9,10)(11,12)(21,22,24,25)(23,26,27,28), (6,8)(10,12)(14,17)(18,20)(22,25)(23,27), (6,8)(10,12)(15,19)(18,20), (13,14)(15,18)(16,17)(19,20)(21,22)(23,26)(24,25)(27,28), (3,4), (1,2)(3,4), (5,6)(7,8)(9,10)(11,12)(13,15)(14,18)(16,19)(17,20)(21,23,24,27)(22,26,25,28));
