Presentation

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

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

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