Presentation

minimal degreeμ(G) = 22
transitive degreeμt(G) = 128

A minimal faithful permutation representation — 7 generators on 22 points:

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