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