Presentation

minimal degreeμ(G) = 32
transitive degreeμt(G) = 256

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

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