Presentation

minimal degree	μ(G) = 19
transitive degree	μ_t(G) = 72

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

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

Polycyclic presentation:

2^2,3^2,2^7|c^a=c^2,d^a=d^2,e^a=f,e^d=f,f^a=e,f^d=ef,g^a=h,g^b=gij,g^d=h,g^f=gk,h^a=g,h^b=hi,h^d=gh,h^e=hk,i^a=ij,i^d=j,j^d=ij
