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.

A274414 Decimal expansion of V_2N, a Quantum Field Theory constant related to the coloring of the tetrahedron with two masses (non-adjacent case).
