Numbers /12,100
How rare is 12,100?
12,100 scores 672 and sits in the Singular tier — 1 in 1,618 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 0.06% 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.
This number's digits add up to an uncommon total.
Arithmetic · signal frequency
An integer squared.
Factorization · signal frequency
Contains a run of three or more consecutive descending digits.
Sequence · signal frequency
This number uses an uncommon count of distinct digits.
Repetition · signal frequency
Divisible by the sum of its digits.
Arithmetic · signal frequency
Two different digits each appear twice.
Repetition · signal frequency
Strongest signal: Digit sum 4. It appears in 126 supported numbers and contributes +259 after correlation decay.
Why is 12,100 unusual? Only 0.06% 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.
Double Pair Numbers
A double pair has two different digits appearing twice each, like 3388 or 271721. It is the digit equivalent of two pair in poker.
Descending Digit Runs
Three or more digits each one lower than the last, appearing anywhere in the number — the 543 inside 15432, for instance.
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.
Perfect Squares
A perfect square is some whole number times itself: 144 = 12², 10000 = 100². The range ends neatly on 1,000,000 = 1000².
