wow, this is a tricky question...
okay, so setting aside all other information about the number 666, and focusing on the bible's intention of the number 666 in revelations, this is what i will conclude. with 7 symbolizing the fullness of god, 666 represents:

The name of the beast
The number representing his name
The number of the Beast
The number of a man
The number is 666

these five clues are found within revelations. so! 666 represents all of these things! basically, shortened down to one small sentence, 666 is the name and number of the antichrist.
