Presentation

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

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

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