Presentation

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

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

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