Presentation

minimal degree	μ(G) = 22
transitive degree	μ_t(G) = 512

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

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

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

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