Presentation

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

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

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

Polycyclic presentation:

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