Presentation

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

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

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

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

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