Presentation

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

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

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

Polycyclic presentation:

2^8|a^2=g,b^2=eg,d^2=f,b^a=be,c^a=cf,e^a=eh,e^b=eh,g^b=gh
