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

Polycyclic presentation:

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