OEIS Sequences

G.f.s of the z^p coefficients of the polynomials in the GF2 denominators of A156925. A157703

Weird untouchable numbers. A357326

Start with x=n, then iterate the map x -> A322982(x) with A322982(x)=2·x-1 if·is noncomposite, otherwise A322982(x) = A032742(x), the largest proper divisor of x. If this iteration leads to a fixed point then a(n) is the value of that fixed point. If the iteration leads to a cycle, a(n) is the smallest value in the cycle. If the iteration never becomes periodic then a(n)=0. A87717

Sum of terms in periodic part of continued fraction expansion of square root of 1+3ⁿ. A77630
