Presentation

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

A minimal faithful permutation representation — 6 generators on 22 points:

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

GAP

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

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