Presentation

minimal degree	μ(G) = 28
transitive degree	μ_t(G) = 256

A minimal faithful permutation representation — 4 generators on 28 points:

(1,2)(3,4)(13,14,16,20,17,18,24,25)(15,21,23,28,22,19,26,27);(2,4)(5,6,8,11,9,7,10,12)(15,22)(19,21)(23,26)(27,28);(5,7,8,12,9,6,10,11)(14,18)(19,21)(20,25)(27,28);(13,15,16,23,17,22,24,26)(14,19,20,27,18,21,25,28)

Polycyclic presentation:
