Presentation

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

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

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

Polycyclic presentation:

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