Presentation

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

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

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

GAP

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

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