Presentation

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

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

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

GAP

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