Presentation

minimal degreeμ(G) = 19
transitive degreeμt(G) = 224

A minimal faithful permutation representation — 3 generators on 19 points:

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

Polycyclic presentation:

2^6,7|b^2=f,c^2=d,e^2=f,c^a=ce,e^a=ef,g^a=g^6,c^b=cf,e^c=ef
