Presentation

minimal degreeμ(G) = 22
transitive degreeμt(G) = 128

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

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

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

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