Presentation

minimal degreeμ(G) = 21
transitive degreeμt(G) = 320

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

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

Polycyclic presentation:

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