Presentation

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

A minimal faithful permutation representation — 4 generators on 19 points:

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

Polycyclic presentation:
