Presentation

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

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

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

GAP

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

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