Presentation

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

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

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