Presentation

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

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

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

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

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