minimal degreeμ(G) = 40
transitive degreeμt(G) = 256

A minimal faithful permutation representation — 3 generators on 40 points:

(1,2,4,7,5,3,8,6)(9,10,13,18,15,19,14,29)(11,20,23,36,25,37,24,40)(12,26,21,34,28,31,27,17)(16,30,32,39,33,38,35,22);(9,11,21,30,14,24,12,22,15,25,27,38,13,23,28,39)(10,16,31,40,18,32,17,20,19,33,26,36,29,35,34,37);(1,3)(2,5)(4,6)(7,8)
