Presentation

minimal degreeμ(G) = 22
transitive degreeμt(G) = 256

A minimal faithful permutation representation — 6 generators on 22 points:

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