AI overview
I don't have enough context to provide an accurate overview of what "464" refers to. Without knowing whether this refers to a year (464 AD/CE), a law or bill number, a product code, or something else entirely, I cannot write a reliable explanation for a general reader.

Kingdom of Syagrius (464)
Year 464 (CDLXIV) was a leap year starting on Wednesday of the Julian calendar. At the time, it was known as the Year of the Consulship of Rusticus and Olybrius (or, less frequently, year 1217 Ab urbe condita). The denomination 464 for this year has been used since the early medieval period, when the Anno Domini calendar era became the prevalent method in Europe for naming years.
