Presentation

minimal degree	μ(G) = 40
transitive degree	μ_t(G) = 128

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

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