Presentation

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

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

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

GAP

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

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