Perfect Cubes

A perfect cube is a whole number raised to the third power: 216 = 6³, 970299 = 99³. There are only about a hundred in the entire range.

Cubes thin out far faster than squares — their density falls like 1 / (3 n^⅔) — so by the time you reach a million there are barely a hundred left. The exact count is above.

This scarcity makes a cube one of the strongest single factorization claims available on the site. Only factorials and powers of two are scarcer.

A number that is both a square and a cube is a sixth power, and there are just a handful of those in range. When both traits fire, the factorization group's decay weighting stops the pair from double counting at full value.
