Presentation

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

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

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

Polycyclic presentation:

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