Presentation

minimal degreeμ(G) = 21
transitive degreeμt(G) = 80

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

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

Polycyclic presentation:

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