Presentation

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

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

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

Polycyclic presentation:

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