Presentation

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

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

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

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

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