A small number. A new bloom.

Arrange digit petals to grow primes. Some have a safe-prime partner and open into golden double blooms.

Grow something curious.

Tap petals in the order you want. Every prime can become a flower; safe-prime pairs bloom twice.

A little experiment is waiting for you.

A peek inside the number notes

A safe prime is a prime p whose (p − 1) / 2 is also prime. For example, 11 and 23 make a pair: 23 = 2 × 11 + 1. The smaller prime is called a Sophie Germain prime. These little numbers are checked exactly by trial division.
