Presentation

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

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

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

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

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