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.
How long might perfect cubes take?
1 in 9,901 per roll · 9,901 rolls on average.
At one daily specimen a day, the mean is about 27.1 years. A 50% chance takes 6,863 rolls; 90% takes 22,797.

1 in 331 chance of at least one match in 30 independent rolls.
Waiting times are averages, not deadlines. Previous misses do not increase the next roll’s chance. Only Daily Specimens stamp your Atlas.
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.

Prime Numbers
A prime has no divisors other than 1 and itself. They are the building blocks every other number is assembled from.
Semiprime Numbers
A semiprime is a product of exactly two primes, counted with multiplicity — 15 = 3 × 5, and 49 = 7 × 7 counts too.
Perfect Squares
A perfect square is some whole number times itself: 144 = 12², 10000 = 100². The range ends neatly on 1,000,000 = 1000².
Powers of Two
Each power of two is double the last: 1, 2, 4, 8, 16, and on up through 1024, 65536 and 524288. Doubling exhausts the range in only twenty steps.
Fibonacci Numbers
Each Fibonacci number is the sum of the two before it: 1, 1, 2, 3, 5, 8, 13 … reaching 832040 before the range runs out.
