Presentation

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

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

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

Polycyclic presentation:

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