Presentation

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

A minimal faithful permutation representation — 2 generators on 32 points:

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