Presentation

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

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

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

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