Presentation

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

A minimal faithful permutation representation — 7 generators on 22 points:

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

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