And for those of you who want even more of the mathematical
properties of 2025, try Diamond Geezer’s excellent blog:

Apparently 2025 is also the square number of a triangular number.

(1+2+3+ ... +8+9)^2 = 45^2 = 2025

The last time it happened was in 1296 = (1+2+3+ ... +8)^2.
Edward I was on the throne at the time.

I bet even Tim hasn’t even noticed that yet!
