cp's OEIS Frontend

This is a front-end for the Online Encyclopedia of Integer Sequences, made by Christian Perfect. The idea is to provide OEIS entries in non-ancient HTML, and then to think about how they're presented visually. The source code is on GitHub.

Comments

Since n! grows faster than 10^n, eventually the entries become 0. This occurs at a(25).

Examples

			a(7) = 4, 1/7! = 1/5040 = 0.0001984126984126984126984126984127... and the seventh digit after the decimal point is 4.
