Michele is right on with her answers.
Here is a five chambered pod that came from a pentamerous bloom. The "numbers" all relate. A pentamerous bloom will have five sets of sepal/petal pairs, five tubes in the pistil and five sections in the ovary which if pollinated will give a five chambered pod. A regular bloom has all of these in threes, a 4x4 poly bloom in sets of fours, etc. That's one of the things that differentiates polys from doubles. Doubles have the extra tepals but not in pairs. It has extra petals and only three tubes to the pistil, three chambers to the pod, etc.

Look at these beauties on Octomom. I'm amazed. I've only had the plant a few weeks.

Smoke Scream is also new this year and has had several poly blooms.
