Presentation

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

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

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