Presentation

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

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

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

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

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