Presentation

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

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

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