Presentation

minimal degreeμ(G) = 22
transitive degreeμt(G) = 512

A minimal faithful permutation representation — 5 generators on 22 points:

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