Presentation

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

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

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

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