Presentation

minimal degreeμ(G) = 20
transitive degreeμt(G) = 64

A minimal faithful permutation representation — 3 generators on 20 points:

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

Polycyclic presentation:

2^9|a^2=f,b^2=dfh,c^2=e,g^2=i,b^a=bd,c^a=ce,d^a=dg,g^a=gh,h^a=hi,d^b=dgi,f^b=fgi,g^b=gh,f^d=fhi,g^d=gi,g^f=gi
