Presentation

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

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

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