Presentation

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

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

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

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

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