Presentation

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

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

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