Presentation

minimal degree	μ(G) = 40
transitive degree	μ_t(G) = 64

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

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