Presentation

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

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

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

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