Presentation

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

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

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

Polycyclic presentation:

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