Presentation

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

A minimal faithful permutation representation — 3 generators on 16 points:

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

Polycyclic presentation:

2^6|a^2=e,c^2=e,d^2=f,e^2=f,b^a=bd,d^a=df,d^b=df
