Presentation

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

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

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