Presentation

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

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

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