Presentation

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

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

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

GAP

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

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