Presentation

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

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

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