Presentation

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

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

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

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

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