Presentation

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

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

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