Presentation

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

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

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

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

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