What are the most common Vault numbers in Fallout Shelter? [closed]

Bethesda has not released any information regarding the most frequently used vault numbers.

However, in my research I have seen Vault 420, Vault 666, and Vault 777 appear most frequently in media and online tutorials. Similarly, these three numbers appear most often in a Reddit post asking the same question. While I cannot verify it, these seem to be the most common numbers for Vault-Tec Vaults.

An honorable mention is any Vaults which appear in the Fallout franchise. I personally named the first Vault I created in Fallout Shelter after the infamous Vault 77 U.S. Government Issue Puppet Ration experiment.
