Presentation

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

A minimal faithful permutation representation — 5 generators on 16 points:

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

Polycyclic presentation:

2^8|a^2=g,d^2=h,b^a=bf,c^a=cg,c^b=ch,e^b=eh,d^c=dh
