x23F4

x23F4 is a short alphanumeric designation that can be found in multiple technical domains, but is not associated with a single, universal reference. Depending on context, it may denote a versioned item, a locus tag in a fictional genome, or a catalog identifier for a component. The canonical form often follows a pattern in which the initial x signals an experimental or cross-domain code, “23” encodes a numeric index, “F” marks a family or feature set, and “4” indicates a revision or variant. Variants of the scheme may omit digits or letters, or repurpose the letters for other categories.

In genetics and bioinformatics education, x23F4 is commonly used as a placeholder example to illustrate how locus tags or accession numbers can be formed, rather than representing a real biological sequence. In electronics or product catalogs, similar codes appear as model numbers or part identifiers, where the letters designate a product family and the digits indicate revision levels. In data management, x23F4-type codes are sometimes used as dataset identifiers or file-name prefixes to encode metadata.

Overall, x23F4 serves as an example of how compact alphanumeric identifiers convey category, sequence, and revision information in a variety of technical contexts. Because there is no single standard associated with x23F4, interpretation relies on the accompanying documentation or metadata.
