What do you mean that each base can be included or excluded? Isn't only one extra value needed? Sort of like nil?

Because there are notations for any combination of bases. There's a way to indicate "C or G", "A or T", "C, G, or A", etc.

Oh. So what's the grand total of all possible permutations of single and multiple (connected with an "or") values?

I'll also read through your links, thanks for posting them.
