Presentation

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

A minimal faithful permutation representation — 7 generators on 22 points:

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

GAP

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

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