Presentation

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

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

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

Polycyclic presentation:
