Puzzle Number 7 Errata

As Scott brought to my attention, part of Puzzle 7 was poorly worded. I have corrected it in the actual post, but wanted to post something quickly pointing that out as well.

Each element of an alphabet must be constructed so that all molecules are bound to at least one other molecule in its network, but not all bonds need to be activated on a given molecule, thus allowing distinct and distinguishable bond networks to be constructed.

This is not worded the most clearly... what I was trying to say was that all elements of the alphabet must be connected (in other words, you cannot have two pairs of bound A molecules that are disconnected), but not all bonds within the network need to be activated. Also, your company can distinguish the difference between different bond arrangements and not just the total number of bonds.
