Presentation

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

A minimal faithful permutation representation — 3 generators on 32 points:

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