Presentation

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

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

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