Presentation

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

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

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