Presentation

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

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

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

Polycyclic presentation:

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