Numbers /6
How rare is 6?
6 scores 1,269 and sits in the Singular tier — 1 in 83,333 of all supported numbers score this high or higher. Everything below is computed from a complete analysis of all 1,000,001 numbers in range.
RNGdle.net’s own rarity score. Top <0.01% means that proportion of supported numbers scores at least this high. Every exact number has the same chance of being rolled. How this differs from EP · Badge guide
These notes make the number easy to read, but they add no score unless a separately counted rarity signal appears below.
Equal to k! for some k.
Factorization · signal frequency
Only 10 of the 1,000,001 supported numbers have one digit.
Range · signal frequency
This number uses an uncommon count of distinct digits.
Repetition · signal frequency
This number's digits add up to an uncommon total.
Arithmetic · signal frequency
A sum 1 + 2 + … + k for some k.
Factorization · signal frequency
Divisible by the sum of its digits.
Arithmetic · signal frequency
The product of exactly two primes.
Factorization · signal frequency
Strongest signal: Factorial. It appears in 9 supported numbers and contributes +335 after correlation decay.
Why is 6 unusual? Only <0.01% of the 1,000,001 supported numbers receive an equal or higher rarity score. This number falls in the Singular tier. Scoring is grounded in the exact frequency of each detected trait — rarer traits carry more information and contribute more to the score.

Patterns in this number
Each of these has its own page explaining how common the pattern is and why.
Harshad Numbers
A Harshad — or Niven — number is divisible by the sum of its own digits. 18 works because 1 + 8 = 9 and 18 ÷ 9 = 2.
Semiprime Numbers
A semiprime is a product of exactly two primes, counted with multiplicity — 15 = 3 × 5, and 49 = 7 × 7 counts too.
Triangular Numbers
A triangular number counts the dots in a triangle: 1, 3, 6, 10, 15, 21 — each one the running total 1 + 2 + … + k.
Factorial Numbers
A factorial multiplies together every whole number up to k: 5! = 120, 7! = 5040, 9! = 362880. The next one after that already overshoots a million.
