Presentation

minimal degreeμ(G) = 32
transitive degreeμt(G) = 64

A minimal faithful permutation representation — 3 generators on 32 points:

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