4BY15

4by15 is a term formed by combining the numbers 4 and 15. It has no single, universally recognized subject and can refer to several distinct things depending on context. In mathematics and design, 4-by-15 indicates a rectangle or grid with 4 rows and 15 columns, totaling 60 units; such grids appear in puzzles, seating charts, fabric cutting, and display layouts. In manufacturing and retail, 4BY15 can function as a part number or model code, indicating a size, variant, or specification within a catalog; capitalization and punctuation vary, including 4BY15, 4by15, or 4-BY-15. In arts and events, the string has occasionally been used as a title or identifier for projects, performances, or releases, though no single notable item bears universal recognition under this exact label. When encountered, the specific meaning of 4by15 is determined by accompanying context such as a brand, product line, or description.
