Presentation

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

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

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

Polycyclic presentation:
