Presentation

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

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

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

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

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