Presentation

minimal degree	μ(G) = 40
transitive degree	μ_t(G) = 256

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

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