Presentation

minimal degree	μ(G) = 40
transitive degree	μ_t(G) = 64

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

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