Presentation

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

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

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

Polycyclic presentation:

2^9,3|b^2=e,c^2=h,d^2=h,f^2=i,c^a=ch,c^b=cf,d^b=dfg,e^c=eh,e^d=eh,f^a=fi,f^b=fhi,f^e=fi,g^a=gi,h^b=hi,j^d=j^2
