Presentation

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

A minimal faithful permutation representation — 5 generators on 32 points:

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