Presentation

minimal degreeμ(G) = 16
transitive degreeμt(G) = 128

A minimal faithful permutation representation — 4 generators on 16 points:

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

Polycyclic presentation:

2^8|b^2=eh,c^2=f,e^2=h,b^a=be,c^a=cf,d^a=dg,e^a=eh
