Kaprekar numbers: positive numbers n such that n = q+r and n² = q·10^m+r, for some m >= 1, q >= 0 and 0 <= r < 10^m, with n ≠ 10^a, a >= 1. A6886

Triangular numbers that are the product of two triangular numbers greater than 1. A188630

Numbers whose decimal expansion contains only 0's and 5's. A169964

a(n) = A069537(n)/2. A88404

a(n) = 10ⁿ*(10ⁿ+1)/2. A37156

Another version of the Kaprekar numbers (A006886): n such that n = q+r and n² = q·10^m+r, for some m >= 1, q >= 0 and 0 <= r < 10^m, with n ≠ 10^a, a >= 1 and n an m-digit number. A53816

Kaprekar numbers: numbers k such that k = q + r and k² = q·10^m + r, for some m >= 1, q >= 0 and 0 <= r < 10^m. Here q and r must both have the same number of digits. A45913
