Presentation

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

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

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

Polycyclic presentation:
