Presentation

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

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

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

Polycyclic presentation:

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