Conventions
The OEIS is currently limited to plain ASCII text, so it uses a linear form of conventional mathematical notation (such as f(n) for functions, n for running variables, etc.). Greek letters are usually represented by their full names, e.g., mu for μ, phi for φ. Every sequence is identified by the letter A followed by six digits, sometimes referred to without the leading zeros, e.g., A315 rather than A000315. Individual terms of sequences are separated by commas. Digit groups are not separated by commas, periods, or spaces. In comments, formulas, etc., a(n) represents the nth term of the sequence.

Famous quotes containing the word conventions:
“I find nothing healthful or exalting in the smooth conventions of society. I do not like the close air of saloons. I begin to suspect myself to be a prisoner, though treated with all this courtesy and luxury. I pay a destructive tax in my conformity.”
—Ralph Waldo Emerson (1803–1882)
“Why does almost everything seem to me like its own parody? Why must I think that almost all, no, all the methods and conventions of art today are good for parody only?”
—Thomas Mann (1875–1955)
“Languages exist by arbitrary institutions and conventions among peoples; words, as the dialecticians tell us, do not signify naturally, but at our pleasure.”
—François Rabelais (1494–1553)
