Presentation

minimal degreeμ(G) = 22
transitive degreeμt(G) = 512

A minimal faithful permutation representation — 7 generators on 22 points:

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

GAP

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

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