Presentation

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

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

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