Presentation

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

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

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

Polycyclic presentation:

2^8|a^2=ef,b^2=e,c^2=e,d^2=h,b^a=be,c^a=cf,d^a=dh,c^b=cg
