Presentation

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

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

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

Polycyclic presentation:

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