Presentation

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

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

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