Presentation

minimal degree	μ(G) = 22
transitive degree	μ_t(G) = 512

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

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

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

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