Presentation

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

A minimal faithful permutation representation — 4 generators on 40 points:

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