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

Polycyclic presentation:

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