Presentation

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

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

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