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

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