Presentation

minimal degreeμ(G) = 40
transitive degreeμt(G) = 128

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

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