Show that R is an equivalence relation

Let $\displaystyle A$ be the set of all bit strings of length 10. Let $\displaystyle R$ be the relation defined on $\displaystyle A$ where two bit strings are related if the third, fourth and last bits are the same. Show that $\displaystyle R$ is an equivalence relation and enumerate one bit string from each of the different equivalence classes of $\displaystyle R$.

I've already proven that $\displaystyle R$ is an equivalence relation, so don't worry about that half of the question.

The second half is what's giving me trouble. I am not entirely sure of how to do this, though I could guess. Since three bits are the same, are there $\displaystyle 2^3=8$ different equivalence classes of $\displaystyle R$?

EDIT: Here's my current answer to the second half. Can someone confirm if it works?
