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.

A355919 Let n = p_1*p_2*...*p_k be the prime factorization of n, with the primes sorted in descending order; let b(n) = 7^(p_1 - 1)*13^(p_2 - 1)*19^(p_3 - 1)*...*A002476(k)^(p_k - 1). Sequence lists m such that b(m) > A343771(m).
