Presentation

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

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

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