Hi!

The propagator of type external for the Fermion (in QED) is given by the following expression:
AnalyticalPropagator[External][ s F[i, mom] ] == NonCommutative
[DiracSpinor[-mom, Mass[F[i]], Sequence@@ @Drop[{i}, 1]] ],

Would you please just tell me what does it mean this:
Sequence@@ @Drop[{i}, 1]]

Thank you in advance
Karima
