Presentation

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

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

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