Presentation

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

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

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