111000111111

111000111111 is a binary numeral string consisting of 12 bits. The sequence contains runs of three consecutive 1s, followed by three 0s, and then six 1s.

When interpreted as an unsigned binary number, it equals 3647 in decimal, and 0xE3F in hexadecimal. If padded to 16 bits for alignment, it can be written as 0000 1110 0011 1111.

The value is within the range of 12-bit numbers (0 to 4095). The decimal value 3647 factors as 7 × 521, so it is not a prime. The pattern is often used illustratively to discuss topics such as bit patterns, masks, and run-length encoding, where the sequence can be described by the lengths of its runs: 3 ones, 3 zeros, and 6 ones.

The string is not a standard constant or widely recognized numeric term; it serves mainly as an example in explanations of binary representation and digital patterning.
