Presentation

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

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

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

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

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