Presentation

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

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

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