8193

8193 is the natural number that comes after 8192 and before 8194. It is of interest in mathematics for its factorization and in computing for its Unicode representation.

In mathematics, 8193 is an odd composite number. Its prime factorization is 3 × 2731, where 2731 is itself a prime. Thus, 8193 is a semiprime (the product of two primes). A related arithmetic property is that numbers of the form 2^n + 1 with n odd are divisible by 3; since 13 is odd, 2^13 + 1 equals 8193, explaining its factorization.

In standard numeral systems, 8193 can be represented as 10000000000001 in binary and 0x2001 in hexadecimal. The decimal value is often used in binary-related discussions because it equals 2^13 + 1.

In computing and text encoding, 8193 corresponds to the Unicode code point U+2001, which is the EM QUAD space. EM QUAD is a typographic space whose width matches the current font’s em, making it a wide whitespace character used in typesetting rather than a visible glyph.

Overall, 8193 is notable mainly for being one more than a power of two (2^13 + 1), for its semiprime factorization, and for its assignment to a specific Unicode space character in the U+2001 code point.
