Presentation

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

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

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

Polycyclic presentation:

2^9|a^2=f,b^2=g,c^2=e,b^a=bd,c^a=ce,d^a=dh,g^a=gi,d^b=di,f^b=fh
