Implementations of select OEIS integer sequences in Python 3.

Two programs that illustrate the creation of OEIS array A089840, which lists signature permutations of non-recursive Catalan automorphisms, that is, bijections of finite plane binary trees, with no unlimited recursion down to indefinite distances from the root.

The least n with rad(n) | f(n) whose covering digraph has girth k, for eleven arithmetic functions and k = 2..10: 52 values proved minimal, 38 of them computed here for the first time, with a surgery theorem on the cycle and a certificate deciding m_f(k+1) < m_f(k) without computing it.
