Presentation

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

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

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

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