Presentation

minimal degreeμ(G) = 28
transitive degreeμt(G) = 256

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

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

Polycyclic presentation:
