Presentation

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

A minimal faithful permutation representation — 5 generators on 40 points:

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