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

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