Presentation

minimal degree	μ(G) = 40
transitive degree	μ_t(G) = 128

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

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