Presentation

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

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

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