Presentation

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

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

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