Ask not what this is --- ask "what is this knot?"

An "attractive" red cube in the middle of this polymer.

An example of the nonmonotonicity of optimal protein folding in the hydrophobic-polar model!

Here's an example of my online game Labbyfold. Fold proteins into their optimal configuration! math.hawaii.edu/~bjoern/?she...

I forget the proper terminology! But the DFA is shown below. The alphabet is {0,1}. Reading 000 you go in a 3-cycle from q₀ to q₀. Given this you can fill in all edge labels. The big diagram above indicates that states (q₀,q₁,q₂) go to (q₁,q₂,q₀) when reading a 0, by having an arrow from 012 to 120.

Thanks --- here's a monoid from my book!
