Presentation

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

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

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

Polycyclic presentation:

2^10|a^2=ij,d^2=ij,f^2=j,d^a=dg,d^b=dg,d^c=dij,e^a=eh,e^d=ef,f^a=fi,f^c=fj,f^e=fj,h^a=hj,h^d=hij,h^f=hj,i^e=ij
