Presentation

minimal degreeμ(G) = 32
transitive degreeμt(G) = 128

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

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