Presentation

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

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

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

GAP

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

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