Okay, so now that I had a way to split the sequences into pieces, I just needed a way to count the number of sequences for each value of , and sum those together.
-The sum was the easy part. I knew the final number would be the the sum of all of the s, or:

After thinking about the sequences for a while, I realized that the number of sequences boils down to the question "how many ways can you uniquely arrange a list of special items out of total items?"

Yay!
The formula on ProofWiki is for the th fibonacci number, so here's how you could arrive at the real Fibonacci Number as Sum of Binomial Coefficients function:
