Presentation

minimal degreeμ(G) = 32
transitive degreeμt(G) = 64

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

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