• Numbers, with an even number of digits, that are the sum of the squares of their two halves (leading zeros allowed only for the second half).at n=4A055616
• Decimal numbers n such that after possibly prefixing leading 0's to n, the resulting number n' can be broken into 2 numbers of equal length, n' = xy, such that x^2+y^2 = n (y may also have leading zeros).at n=9A064942
• Decimal numbers n such that after possibly prefixing a leading 0 to n, the resulting number n' can be broken into 2 strings of the same length, n' = xy, such that x^2+y^2 = n.at n=7A101311
• Numbers k with the property that there exist nonnegative integers a and b such that k = concat(a,b) = a^2+b^2.at n=10A178530
• Positive integers of the form x*10^k + y which also equal x^2 + y^2 (x, y and k being positive integers).at n=12A275986
• Numbers k whose decimal expansion can be split into two parts s and t with k = s^2 + t^2.at n=7A368416
