Presentation

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

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

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

Polycyclic presentation:

2^8|a^2=g,d^2=e,f^2=h,b^a=be,c^a=cf,d^a=de,c^b=ce,f^c=fh,g^c=gh
