Presentation

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

A minimal faithful permutation representation — 3 generators on 21 points:

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

Polycyclic presentation:

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