Presentation

minimal degree	μ(G) = 22
transitive degree	μ_t(G) = 64

A minimal faithful permutation representation — 4 generators on 22 points:

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

GAP

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

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