Presentation

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

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

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

Polycyclic presentation:
