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

Polycyclic presentation:

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