Presentation

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

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

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

GAP

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

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