I gather you mean the "666" section.
Your guess is as good as mine. I think that the 6+6+6=18=9 is base. Base 9 is non-productive. 9x7=63. 6=3=9
When the product always equals the input it is non-productive. This is the base lifestyle, in the ego. So I think if there is any design to the number of the Section for the FrivPen, it is to scare Christians into paying up. But while I am guessing, the FrivPen went up from $500 to $5000 when we began redeeming lawful money. So it may have been based on scaring me, thinking that I must be a religious leader.
However, I think that cause and effect are different than what most people do, or what I used to think it was. So it simply makes more sense that statute should be aligned to the Base Chakra - thinking with the gonads.
