Presentation

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

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

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