Presentation

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

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

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

Polycyclic presentation:

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