Presentation

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

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

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

GAP

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

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