Presentation

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

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

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