Presentation

minimal degreeμ(G) = 22
transitive degreeμt(G) = 128

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

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

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