Presentation

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

A minimal faithful permutation representation — 5 generators on 22 points:

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

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

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