Presentation

minimal degree	μ(G) = 27
transitive degree	μ_t(G) = 224

A minimal faithful permutation representation — 3 generators on 27 points:

(1,2,4,6,7,5,3)(9,11)(12,14,16,22)(13,18,17,26)(15,24,25,21)(19,27,23,20);(8,9,10,11)(13,17)(18,26)(19,23)(20,27);(2,3)(4,5)(6,7)(9,11)(12,13)(14,20)(15,23)(16,17)(18,21)(19,25)(22,27)(24,26)

Polycyclic presentation:
