Presentation

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

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

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

Polycyclic presentation:

2^11|a^2=e,b^a=bf,c^a=cj,c^b=cg,d^a=dh,e^b=ei,e^d=ej,f^a=fi,f^c=fjk,f^e=fk,g^a=gjk,h^a=hj,i^a=ik
