Presentation

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

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

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

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

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