Presentation

minimal degreeμ(G) = 16
transitive degreeμt(G) = 64

A minimal faithful permutation representation — 4 generators on 16 points:

(2,6)(3,4)(7,8)(9,10,13,15,14,11,12,16);(1,2)(3,6)(4,8)(5,7)(9,11)(10,14)(12,15)(13,16);(1,3,5,4)(2,6,7,8)(9,12,14,13)(10,15,11,16);(1,3,5,4)(2,6,7,8)(9,12,14,13)(10,16,11,15)
