Presentation

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

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

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

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

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