Presentation

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

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

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