Presentation

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

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

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

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

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