Presentation

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

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

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