Presentation

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

A minimal faithful permutation representation — 7 generators on 22 points:

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

GAP

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

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