Presentation

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

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

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

GAP

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

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