Presentation

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

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

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

GAP

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