Presentation

minimal degreeμ(G) = 22
transitive degreeμt(G) = 128

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

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

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

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