Presentation

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

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

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

Polycyclic presentation:

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