Numbers /5,040
How rare is 5,040?
5,040 scores 813 and sits in the Singular tier — 1 in 5,882 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 0.02% 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
This number's digits add up to an uncommon total.
Arithmetic · signal frequency
One of 9,000 four-digit numbers in range.
Range · signal frequency
This number uses an uncommon count of distinct digits.
Repetition · signal frequency
Every comparison strictly alternates between rising and falling.
Sequence · signal frequency
Divisible by the sum of its digits.
Arithmetic · signal frequency
Exactly one digit appears twice.
Repetition · signal frequency
Strongest signal: Factorial. It appears in 9 supported numbers and contributes +335 after correlation decay.
Why is 5,040 unusual? Only 0.02% 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.
Numbers With One Repeated Digit
The mildest form of repetition: exactly one digit appears twice, and every other digit is distinct — as in 1231 or 405067.
Zigzag Digit Numbers
Every comparison changes direction: up, down, up, down — or the reverse. In 792619 the path is 7 < 9 > 2 < 6 > 1 < 9.
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.
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.
