Presentation

minimal degreeμ(G) = 28
transitive degreeμt(G) = 128

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

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

Polycyclic presentation:
