Presentation

minimal degreeμ(G) = 32
transitive degreeμt(G) = 128

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

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