Presentation

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

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

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

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