Appears in sequences

• Column 0 of triangle A118032, where column 0 of the matrix square of A118032 forms a bisection of this sequence.at n=25A118033
• Column 0 of triangle A118045; also equals a bisection of A118033, which is column 0 of A118032.at n=12A118046
• 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.at n=42A133392
• Numbers k such that k and k^2 use only the digits 0, 2, 4, 7 and 8.at n=49A136906
• Coefficients in the expansion of 1/([r] + [2r]x + [3r]x^2 + ...); [ ] = floor, r = 8/5.at n=20A279780
• Coefficients in the expansion of 1/([r]-[2r]x+[3r]x^2-...); [ ]=floor, r=8/5.at n=20A289260
