Suppose there exists a radio station, “WACD 902 AM, The Sturge”. The number represents the frequency of the radio wave in megahertz. Now why did they choose that specific frequency? Did they have a specific preference for that number? Or more likely, they just chose whatever was available.
I’m not sure you understand what “arbitrary” means.
Those numbers are not random or without reason.
They are not random, but what is the rationale?
