Presentation

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

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

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

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

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