Online Encyclopedia of Integer sequences (referring to my contributions)
The
OEIS
(The OnLine Encyclopedia of Integer Sequences),
founded in 1964 by N.J.A. Sloane, contains
a large number of data about integer sequences;
for a detailed descriptions of its aims see
their Welcome page.
Some research contributions of mine were inserted in the encyclopedia.
They are listed here:
