Presentation

minimal degreeμ(G) = 40
transitive degreeμt(G) = 1920

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

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