Presentation

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

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

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

Polycyclic presentation:

2^9,3|b^2=e,f^2=i,c^b=cefi,d^a=dh,d^b=dg,e^c=eh,f^b=fh,f^c=fh,f^e=fi,g^a=gi,h^b=hi,j^c=j^2
