Presentation

minimal degree	μ(G) = 22
transitive degree	μ_t(G) = 512

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

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

GAP

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

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