Presentation

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

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

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