Presentation

minimal degreeμ(G) = 19
transitive degreeμt(G) = 224

A minimal faithful permutation representation — 3 generators on 19 points:

(1,2,4,6,7,5,3)(12,13,14,16,15,17,18,19);(8,9,10,11);(2,3)(4,5)(6,7)(9,11)(13,16)(14,18)(17,19)

Polycyclic presentation:

2^6,7|b^2=e,c^2=d,d^2=f,b^a=be,c^a=cd,d^a=df,g^a=g^6
