Presentation

minimal degreeμ(G) = 21
transitive degreeμt(G) = 320

A minimal faithful permutation representation — 2 generators on 21 points:

(1,2,4,5,3)(6,7,8,10,9,11,12,13)(15,18)(16,21)(19,20);(2,3)(4,5)(14,15,17,20)(16,18,21,19)

Polycyclic presentation:

2^6,5|a^2=f,b^2=c,c^2=e,d^2=f,b^a=bd,d^a=df,g^a=g^4,d^b=df
