Presentation

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

A minimal faithful permutation representation — 5 generators on 22 points:

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

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

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