Presentation

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

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

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