Presentation

minimal degree	μ(G) = 21
transitive degree	μ_t(G) = 54

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

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

Polycyclic presentation:

2^2,3^6|c^a=ch^2,c^b=ch^2,d^b=d^2,d^c=dg,e^b=e^2,f^a=f^2,f^b=fh^2,f^d=fh,g^b=g^2,h^a=h^2,h^b=h^2
