Presentation

minimal degreeμ(G) = 19
transitive degreeμt(G) = 48

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

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

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^b=df,d^c=dh,e^a=ei,e^d=eh,f^b=fi,f^c=fh,f^e=fi,g^a=gi,h^b=hi,j^c=j^2
