Presentation

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

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

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