Presentation

minimal degreeμ(G) = 16
transitive degreeμt(G) = 120

A minimal faithful permutation representation — 2 generators on 16 points:

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

Polycyclic presentation:

2^4,3,5|a^2=c,b^2=d,c^2=d,e^a=e^2,f^a=f^3,f^c=f^4
