Presentation

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

A minimal faithful permutation representation — 3 generators on 21 points:

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

Polycyclic presentation:

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