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.

A122957 Numbers n such that if m > n, phi(m) >= phi(n).

Conjecture: except for 1,2,3,4, this is the nonzero values of A066362.

Examples

			10 is in the sequence because phi(10) = 4 and no larger m has phi(m) < 4. phi(12) = 4; it is not smaller.
