• Consider all ways of writing a number as p+2m^2 where p is 1 or a prime and m >= 0; sequence gives numbers that are expressible in at least 2 more ways than any smaller number.at n=24A016067
• Transform of the finite sequence (1, 0, -1) by the T_{1,1} transformation (see link).at n=12A159329
• Expansion of Product_{k>=1} 1/(1 - x^(2*k+1))^k.at n=47A263150
• a(n) = a(n-1) + a(n-2) + gcd(a(n-1), n), a(1) = a(2) = 1.at n=21A360884
