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.

A256985 Define a sequence {b(i), i >= 0} by b(i) = 1 for 0 <= i <= n, thereafter b(i+1) = (b(i)+b(i-n)) mod 10; consider the sequence of n-tuples [b(i-n+1), b(i-n+2),...,b(i)]; this repeats with period a(n).
