Presentation

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

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

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

GAP

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

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