Presentation

minimal degree	μ(G) = 19
transitive degree	μ_t(G) = 48

A minimal faithful permutation representation — 4 generators on 19 points:

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

Polycyclic presentation:

2^9,3|a^2=h,b^2=i,d^2=h,f^2=i,b^a=bg,c^a=ch,c^b=ce,d^a=dh,d^b=df,d^c=dh,e^a=ei,e^d=eh,f^a=fi,f^b=fi,f^c=fh,f^e=fi,g^a=gi,h^b=hi,j^c=j^2,j^d=j^2
