Presentation

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

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

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

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

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