Presentation

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

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

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