Presentation

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

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

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

GAP

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

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