Presentation

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

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

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

Polycyclic presentation:

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