Presentation

minimal degreeμ(G) = 16
transitive degreeμt(G) = 32

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

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

Polycyclic presentation:

2^8|a^2=h,b^a=bf,c^a=cg,e^a=ef,d^b=df
