Presentation

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

A minimal faithful permutation representation — 7 generators on 22 points:

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

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

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