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.

“Art, it seems to me, should simplify. That, indeed, is very nearly the whole of the higher artistic process; finding what conventions of form and what detail one can do without and yet preserve the spirit of the wholeso that all that one has suppressed and cut away is there to the readers consciousness as much as if it were in type on the page.”
—Willa Cather (18731947)
“What people dont realize is that intimacy has its conventions as well as ordinary social intercourse. There are three cardinal rulesdont take somebody elses boyfriend unless youve been specifically invited to do so, dont take a drink without being asked, and keep a scrupulous accounting in financial matters.”
—W.H. (Wystan Hugh)
