Presentation

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

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

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