 Unique Necklaces (Posted on 2004-08-18)

There is no clasp to identify a specific point on the chain, and a flipped over necklace is still the same necklace.
_____________________________

To get you started:

With 1 bead, the necklace can be either 1 black or 1 white bead.

With 2 beads, the necklace can be either 2 black, 2 white, or 1 black-1 white

With 3 beads, the necklace can be either 3 black, 3 white, 2 black-1 white, 2 white-1 black, etc...

```# Beads  Number of Necklaces
1          2
2          3
3          4
4          6
5          8
6         13
```
