Coefficients in the expansion of 1/([r] + [2r]x + [3r]x² + ...); [ ] = floor, r = 8/5. A279780

Column 0 of triangle A118045; also equals a bisection of A118033, which is column 0 of A118032. A118046

Coefficients in the expansion of 1/([r]-[2r]x+[3r]x²-...); [ ]=floor, r=8/5. A289260

Start with a(1)=1; for n >= 1, a(n+1)=a(n)+a(k) with k=[n-n-th digit of "e"]. If k<0 or k=0, then a(k)=0. A133392

Numbers k such that k and k² use only the digits 0, 2, 4, 7 and 8. A136906
