Presentation

minimal degree	μ(G) = 28
transitive degree	μ_t(G) = 128

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

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

Polycyclic presentation:
