minimal degreeμ(G) = 40
transitive degreeμt(G) = 128

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

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