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

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