Presentation

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

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

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

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

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