Presentation

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

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

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