Presentation

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

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

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

GAP

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

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