minimal degreeμ(G) = 40
transitive degreeμt(G) = 64

A minimal faithful permutation representation — 2 generators on 40 points:

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