Presentation

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

A minimal faithful permutation representation — 3 generators on 40 points:

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