Presentation

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

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

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