Presentation

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

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

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

Polycyclic presentation:

2^6,5|b^2=cd,c^2=ef,e^2=f,b^a=bc,c^a=ce,e^a=ef,g^a=g^4,c^b=cf,d^b=df
