Presentation

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

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

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

Polycyclic presentation:

2^6|a^2=f,b^2=df,c^2=e,d^2=f,b^a=bd,c^a=ce,d^a=df
