Presentation

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

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

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

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

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