Presentation

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

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

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

Polycyclic presentation:

2^8|a^2=g,b^2=eg,c^2=e,g^2=h,b^a=be,c^a=cf,d^a=dh,d^b=dh
