Numbers /86,221
How rare is 86,221?
86,221 scores 204 and sits in the Notable tier — 31.39% 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 31.4% 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 5 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
The product of exactly two primes.
Factorization · signal frequency
This number uses an uncommon count of distinct digits.
Repetition · signal frequency

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.
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.
