Presentation

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

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

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

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

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