Presentation

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

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

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