Presentation

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

A minimal faithful permutation representation — 4 generators on 28 points:

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

Polycyclic presentation:
