Presentation

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

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

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