 OFFSET 0,1 COMMENTS Positive values of the polynomial for x,y >= 0 are the Fibonacci numbers. See A000045. Ribenboim discusses the equation on page 193. REFERENCES Ribenboim, P. The New Book of Prime Number Records. New York: Springer-Verlag, p. 193, 1996. LINKS EXAMPLE For x=2, y=1, the value of the polynomial is -23, so 23 is in the sequence. CROSSREFS Cf. A000045.
