Presentation

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

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

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