How rare is 678,817?
678,817 scores 332 and sits in the Exceptional tier — 2.91% 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 2.91% 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
Contains a run of three or more consecutive ascending digits.
Sequence · signal frequency
The product of exactly two primes.
Factorization · signal frequency
Two different digits each appear twice.
Repetition · signal frequency
Iterating the sum of squared digits reaches 1.
Arithmetic · signal frequency
This number uses an uncommon count of distinct digits.
Repetition · signal frequency
Strongest signal: Digit sum 37. It appears in 21,582 supported numbers and contributes +111 after correlation decay.
Why is 678,817 unusual? Only 2.91% of the 1,000,001 supported numbers receive an equal or higher rarity score. This number falls in the Exceptional 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.
Ascending Digit Runs
A partial climb: somewhere in the number sit three or more digits each one higher than the last, as in the 456 inside 74560.
Happy Numbers
Square each digit, add them up, repeat. If you eventually reach 1 the number is happy; if not, you fall into a cycle. 19 → 82 → 68 → 100 → 1.
Semiprime Numbers
A semiprime is a product of exactly two primes, counted with multiplicity — 15 = 3 × 5, and 49 = 7 × 7 counts too.
