This name has been in the main database since at least February 2007, but so far, its latinized form Nicomachus has never made it to the main database.

Not to mention that there are several notable bearers of the name, such as the father and son of the famous Greek philosopher Aristotle (4th century BC): https://en.wikipedia.org/wiki/Nicomachus_(disambiguation) (in English).
