Presentation

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

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

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

Polycyclic presentation:

2^9|a^2=h,f^2=i,g^2=i,h^2=i,b^a=be,c^a=cf,e^a=ei,f^a=fi,g^a=gi,c^b=cg,d^b=def,f^b=fi,g^b=gi,h^b=hi,d^c=de,f^c=fi,g^c=gi,f^d=fi,g^d=gi
