Presentation

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

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

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