A minimal faithful permutation representation — 8 generators on 28 points:
(14,17)(15,19)(21,22,24,25)(23,27,28,26);(3,4);(6,9)(7,11)(14,17)(15,19)(22,25)(23,28);(1,2)(3,4);(6,9)(7,11)(14,17)(18,20)(23,28)(26,27);(6,9)(10,12)(14,17)(18,20);(5,6,8,9)(7,10,11,12)(13,14,16,17)(15,18,19,20)(21,23,24,28)(22,26,25,27);(5,7,8,11)(6,10,9,12)(13,15)(14,18)(16,19)(17,20)(21,22)(23,26)(24,25)(27,28)356 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((14,17)(15,19)(21,22,24,25)(23,27,28,26), (3,4), (6,9)(7,11)(14,17)(15,19)(22,25)(23,28), (1,2)(3,4), (6,9)(7,11)(14,17)(18,20)(23,28)(26,27), (6,9)(10,12)(14,17)(18,20), (5,6,8,9)(7,10,11,12)(13,14,16,17)(15,18,19,20)(21,23,24,28)(22,26,25,27), (5,7,8,11)(6,10,9,12)(13,15)(14,18)(16,19)(17,20)(21,22)(23,26)(24,25)(27,28));
