Presentation

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

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

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