Don't be silly Faldax, you know that only The Beast can change the Number of the Beast which is 666 so stop hypothesizing least people find you a False Beast.

Listen, Falsedo...
The numerical mysterium to correct your roman math is...
DCLXVI = 666
Minus L (50) to rid man-so-unkind of "Lust"
equals 616
Which is the Mark of the Effete Beast.

Oh my!
