Presentation

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

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

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

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

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