Remarks on the Egyptian 2/D table in favor of a global approach (D composite number)
Lionel Bréhamet
Egyptian decompositions of 2/D as a sum of two unit fractions are studied by means of certain divisors of D, namely r and s. Our analysis does not concern the method to find r and…

Remarks on the Egyptian 2/D table in favor of a global approach (D prime number)
Lionel Bréhamet
For h=3 or 4, Egyptian decompositions into h unit fractions, like 2/D = 1/D1 + ... +1/Dh, were given by using (h-1) divisors (di) of D1. This ancient modus operandi, well recognize…
