Presentation

minimal degreeμ(G) = 22
transitive degreeμt(G) = 256

A minimal faithful permutation representation — 8 generators on 22 points:

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

GAP

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

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