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

Polycyclic presentation:
