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.

Primes p in A022011 belong to 11 (mod 210), thus a(n) is congruent to the product of residues {11, 13, 17, 19, 23, 29, 31, 37} (mod 210), i.e., 1 (mod 210).
Gaps between primes are {2, 4, 2, 4, 6, 2, 6}.
