Presentation

minimal degreeμ(G) = 22
transitive degreeμt(G) = 512

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)(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)(17,22,21,20), (15,16)(17,20)(18,19)(21,22), (3,4)(5,6)(15,17)(16,20)(18,21)(19,22), (1,2));
