Presentation

minimal degree	μ(G) = 22
transitive degree	μ_t(G) = 256

A minimal faithful permutation representation — 6 generators on 22 points:

(4,5)(7,8)(9,10)(11,12,13,14)(15,16,18,20)(17,21,22,19);(3,4)(5,6)(15,17)(16,19)(18,22)(20,21);(4,5)(12,14)(16,20)(19,21);(7,8,9,10)(11,12)(13,14)(15,17)(16,21)(18,22)(19,20);(1,2);(3,5,6,4)(7,8)(9,10)(11,12)(13,14)(15,16)(17,19)(18,20)(21,22)

GAP

Past the SmallGroups library coverage — no SmallGroups id. Construct it from a minimal faithful permutation representation:

gap> G := Group((4,5)(7,8)(9,10)(11,12,13,14)(15,16,18,20)(17,21,22,19), (3,4)(5,6)(15,17)(16,19)(18,22)(20,21), (4,5)(12,14)(16,20)(19,21), (7,8,9,10)(11,12)(13,14)(15,17)(16,21)(18,22)(19,20), (1,2), (3,5,6,4)(7,8)(9,10)(11,12)(13,14)(15,16)(17,19)(18,20)(21,22));
