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

Polycyclic presentation:
