Presentation

minimal degreeμ(G) = 21
transitive degreeμt(G) = 160

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

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

Polycyclic presentation:

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