Presentation

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

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

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