Presentation

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

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

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

Polycyclic presentation:

2^5,5|a^2=c,b^2=de,c^2=e,d^2=e,b^a=bd,d^a=de,f^a=f^2,f^c=f^4
