Presentation

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

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

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