Did you know Arlington National Cemetary is 639 acres?
I found the number interesting...639
Tesla 369, Theory of Nikola Tesla's 369, there are all together 1 to 9 digital root numbers exist. All other higher or lower numbers are the combination of those digital root numbers. This statement seems quite true when we compare it with Theory of Absolutivity.
639 in Gematria is interesting. Everything has meaning.
No coincidences!
