Presentation

minimal degreeμ(G) = 32
transitive degreeμt(G) = 256

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

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