Presentation

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

A minimal faithful permutation representation — 2 generators on 40 points:

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