How rare is 555,199?
555,199 scores 272 and sits in the Rare tier — 8.94% 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 8.94% means that proportion of supported numbers scores at least this high. Every exact number has the same chance of being rolled. Same-length rank keeps the score and compares only numbers with 6 digits, including ties. 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.
This number's digits add up to an uncommon total.
Arithmetic · signal frequency
Three or more identical digits in a row.
Repetition · signal frequency
The product of exactly two primes.
Factorization · signal frequency
This number uses an uncommon count of distinct digits.
Repetition · signal frequency
A single digit appears exactly three times.
Repetition · signal frequency
Strongest signal: Digit sum 34. It appears in 35,127 supported numbers and contributes +97 after correlation decay.
Why is 555,199 unusual? Only 8.94% of the 1,000,001 supported numbers receive an equal or higher rarity score. This number falls in the Rare 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.
Triple Digits
A triple contains exactly three copies of one digit, such as 8188 or 636306. It is the most common form of strong repetition — and the first one most people notice.
Adjacent Digit Runs
A run is three or more identical digits sitting next to each other, like the 777 inside 27773. Adjacency is what makes a run read as deliberate.
Semiprime Numbers
A semiprime is a product of exactly two primes, counted with multiplicity — 15 = 3 × 5, and 49 = 7 × 7 counts too.
