Presentation

minimal degreeμ(G) = 32
transitive degreeμt(G) = 760

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

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