Presentation

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

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

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

GAP

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

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