Ah number 666, this is one of my favourite numbers.
It displays an attractive symmetry.
Each 6 is an elementary one-turn spiral, and the triple spiral was the mark (inferentially, when I have my archaeological hat on) of pre-christian Neolithic-Age female deities. viz. the triple goddess.
Christians of course hated the pre-existing female divinities, and resolved to eliminate them by empowering their patriarchal church system to do so.
A godbot told me recently that he would never buy an auto with 666 on it. He was terrified at the superstitious thought, and told me that by accident a friend of his, some years ago, had, without noticing, bought such a vehicle--and very quickly got rid of it again.
