Presentation

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

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

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