Numbers /876,543
How rare is 876,543?
876,543 scores 534 and sits in the Extreme tier — 1 in 524 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 0.19% 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.
Every digit is exactly one lower than the previous, like 9876.
Sequence · signal frequency
This number's digits add up to an uncommon total.
Arithmetic · signal frequency
This number uses an uncommon count of distinct digits.
Repetition · signal frequency
The product of exactly two primes.
Factorization · signal frequency
Digits strictly alternate between odd and even.
Sequence · signal frequency
Strongest signal: Sequential descending. It appears in 26 supported numbers and contributes +305 after correlation decay.
Why is 876,543 unusual? Only 0.19% of the 1,000,001 supported numbers receive an equal or higher rarity score. This number falls in the Extreme tier. Scoring is grounded in the exact frequency of each detected trait — rarer traits carry more information and contribute more to the score.
Algorithm version 1.1.0
One digit away
You found a local peak.
Every legal one-digit neighbour has an equal or lower score.
53 legal neighbours · same digit length · no leading zeros. This describes an alternative number, not the odds of your next roll.

Patterns in this number
Each of these has its own page explaining how common the pattern is and why.
Descending Sequence Numbers
Each digit is exactly one lower than the previous: 321, 6543, 987654. The mirror image of an ascending sequence, and just as scarce.
Alternating Odd and Even Digits
Odd, even, odd, even — or the reverse — all the way through, as in 385274 or 1614. The digits themselves are free; only their parity is constrained.
Semiprime Numbers
A semiprime is a product of exactly two primes, counted with multiplicity — 15 = 3 × 5, and 49 = 7 × 7 counts too.
