Presentation

minimal degreeμ(G) = 22
transitive degreeμt(G) = 256

A minimal faithful permutation representation — 6 generators on 22 points:

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

GAP

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

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