Presentation

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

A minimal faithful permutation representation — 3 generators on 32 points:

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