If you mean polypeptide rather than polysaccharide, for a given set 6 amino acids that all have to be used the answer is 6!. For a given set 6 amino acids that don't all have to be used the answer is 6^6. If you can use any amino acids, but must use 6, the answer is \frac{20!}{14!}

If you weren't talking about polypeptides, I confess that I don't know what you are talking about.

It's asking how many unique polypeptides (not polysaccharides, those are sugars not proteins) you can make using 6 building blocks - amino acids. 6^6 = 46656. If you wanna be pedantic, the single amino acids aren't polypeptides, so 46656 - 6 = 46650.
