Don't forget to write 2025 as
1³+2³+3³+4³+5³+6³+7³+8³+9³
(next opportunity is only in 3025)!
(Or, for the #math and #LaTeX lovers:
\begin{equation}
\sum_{n=1}^9 n^3
\end{equation})

Interesting 2025

1) 2025, itself is a square (45 x 45)

2) It's a product of two squares: 9² x 5² = 2025

3) It is the sum of 3-squares: 40² + 20² + 5² = 2025

4) It's the first square after 1936 (44 x 44)

5) It's the sum of cubes of all the single digits: from 1 to 9 it would be 1³+2³+3³+4³+5³+6³+7³+8³+9³= 2025.

This is going to be our UNIQUE YEAR.

@kevinrns @appassionato You may include 0(zero) to the set of all single digit decimals. It will still work.
