Presentation

minimal degree	μ(G) = 20
transitive degree	μ_t(G) = 64

A minimal faithful permutation representation — 5 generators on 20 points:

(13,14)(15,17)(16,18)(19,20);(1,2)(3,4);(6,9)(7,11)(10,12)(15,20)(17,19);(6,10)(9,12);(2,4)(5,6,7,9,8,10,11,12)(14,17,18,19)

Polycyclic presentation:

2^10|e^2=f,f^2=i,h^2=j,e^a=eh,e^b=eg,e^c=ef,e^d=ei,f^a=fj,f^c=fi,h^a=hj,h^c=hj
