A minimal faithful permutation representation — 5 generators on 21 points:
(1,2)(4,5)(14,15,16,19,17,18,20,21);(2,3,4,5);(6,8,9,12)(7,11,10,13)(15,18)(19,21);(7,10)(11,13);(6,7)(8,11)(9,10)(12,13)250 conjugacy classes — view the full character table.
Past the SmallGroups library coverage — no SmallGroups id. Construct it from a minimal faithful permutation representation:
gap> G := Group((1,2)(4,5)(14,15,16,19,17,18,20,21), (2,3,4,5), (6,8,9,12)(7,11,10,13)(15,18)(19,21), (7,10)(11,13), (6,7)(8,11)(9,10)(12,13));
