A minimal faithful permutation representation — 7 generators on 28 points:
(8,12)(10,11)(14,17)(15,19)(21,22,24,26)(23,25,27,28);(5,6,9,7)(8,11,12,10)(13,14,16,17)(15,20,19,18)(21,22,24,26)(23,25,27,28);(23,27)(25,28);(3,4);(5,7,9,6)(8,11,12,10)(13,15,16,19)(14,18,17,20)(21,23)(22,25)(24,27)(26,28);(1,2)(3,4);(5,8)(6,10)(7,11)(9,12)(13,14)(15,18)(16,17)(19,20)(21,22)(23,28)(24,26)(25,27)280 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((8,12)(10,11)(14,17)(15,19)(21,22,24,26)(23,25,27,28), (5,6,9,7)(8,11,12,10)(13,14,16,17)(15,20,19,18)(21,22,24,26)(23,25,27,28), (23,27)(25,28), (3,4), (5,7,9,6)(8,11,12,10)(13,15,16,19)(14,18,17,20)(21,23)(22,25)(24,27)(26,28), (1,2)(3,4), (5,8)(6,10)(7,11)(9,12)(13,14)(15,18)(16,17)(19,20)(21,22)(23,28)(24,26)(25,27));
