Presentation

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

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

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

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

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