Presentation

minimal degree	μ(G) = 20
transitive degree	μ_t(G) = 128

A minimal faithful permutation representation — 4 generators on 20 points:

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

Polycyclic presentation:

2^10|a^2=g,c^b=cg,d^a=dh,d^b=df,d^c=de,e^b=ei,f^c=fij,f^e=fj,i^d=ij
