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

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

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