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.

A374918 Even numbers k such that lambda(sum of even divisors of k) = phi(sum of odd divisors of k) where lambda is the Carmichael function (A002322) and phi the Euler totient function (A000010).
