Presentation

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

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

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