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

Polycyclic presentation:
