Presentation

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

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

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

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