Presentation

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

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

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