Presentation

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

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

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

Polycyclic presentation:

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