Presentation

minimal degreeμ(G) = 32
transitive degreeμt(G) = 64

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

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