Presentation

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

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

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