OEIS Sequences

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

Kaprekar triples: q such that q = x + y + z and q³ = x·10²ⁿ + y·10ⁿ + z, where z < 10ⁿ and n is the number of digits in q. q is not a power of 10 (except q=1). A6887

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

Kaprekar numbers, allowing powers of 10: n such that n=q+r and n²=q·10^m+r, for some m >= 1, q>=0 and 0<=r<10^m. A248353

Numbers of the form N = a+b+c such that N³ = concat(a,b,c); a, b, c > 0. A328198
