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

GAP

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

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