After learning that 2025 = 0^3 + 1^3 + 2^3 + 3^3 + 4^3 + 5^3 + 6^3 + 7^3 + 8^3 + 9^3, one of my colleagues drew this.

If numbers of the form ∑ᵢ₌₀ᴺ i are triangular numbers, and ∑ᵢ₌₀ᴺ i² are square pyramidal numbers, what do we call a number like the one above? "a cubic hyper-pyramidal number"?

Harold Cooper has created a wonderful web page about ways to visualize these numbers:

Also: 2025 = sum of cubes of all the digits of base 10. Base 2 gives 1. Base 16 gives 14400
