Presentation

minimal degreeμ(G) = 21
transitive degreeμt(G) = 80

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

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

Polycyclic presentation:

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