Presentation

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

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

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

Polycyclic presentation:

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