Presentation

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

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

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

GAP

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

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