Presentation

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

A minimal faithful permutation representation — 4 generators on 32 points:

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