Presentation

minimal degreeμ(G) = 22
transitive degreeμt(G) = 64

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

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

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

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