Presentation

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

A minimal faithful permutation representation — 3 generators on 28 points:

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

Polycyclic presentation:
