Presentation

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

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

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