Presentation

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

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

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

Polycyclic presentation:
