Presentation

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

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

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

Polycyclic presentation:

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