Presentation

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

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

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

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