Presentation

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

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

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

Polycyclic presentation:

2^8|a^2=f,b^2=g,b^a=bd,c^a=ce,d^a=dh,e^b=eh,f^b=fh,d^c=dh
