1oo1

1oo1 is a string composed of the characters 1, o, o, 1, where the middle characters are the lowercase letter o. In many contexts it is treated as a stylized form of the decimal number 1001, and it can function as a palindrome or symmetric motif. Because the letter o resembles the digit 0, the sequence often invites interpretations that blend numeric and alphabetic typography.

Origins and usage vary by domain. In graphic design and branding, designers may use 1oo1 as a logo-like mark or typographic motif to achieve a distinctive, rounded look while evoking the idea of a simple numeric sequence. In puzzles, games, or digital art, 1oo1 can serve as an obfuscated or stylized representation of 1001, sometimes to create a visual puzzle or to convey symmetry. The exact meaning is therefore context-dependent and not tied to a single canonical definition.

Typography and readability considerations are common with 1oo1. Depending on font choice, the characters o and 0 can be difficult to distinguish, which may lead to ambiguity between 1oo1 and 1001 in print or on small screens. This ambiguity is part of its visual appeal in some uses but can be a drawback in contexts requiring precise transcription.
