Presentation

minimal degreeμ(G) = 32
transitive degreeμt(G) = 128

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

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