Presentation

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

A minimal faithful permutation representation — 2 generators on 32 points:

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