Presentation

minimal degreeμ(G) = 32
transitive degreeμt(G) = 256

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

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