Presentation

minimal degreeμ(G) = 22
transitive degreeμt(G) = 256

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

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

GAP

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

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