### Are they in the same sequence?

The familiar Fibonacci sequence can be extended easily to negative indices by the relation F(n-1) = F(n+1) - F(n). It is also possible to create a new (double-ended) Fibonacci-like sequence G from any ordered integer pair (a, b) by setting G(0) = a, G(1) = b, G(n) + G(n+1) = G(n+2) for all integers ...

### Re: Geometry problem.

I figured out how to create a neat* circle incident to A and B where those points don't even have to be inside the circle. However, this was done without a D-construction. The key was that there exists a point A' in the plane such that a circle is incident with both A and A' iff that circle is neat....

### Re: You can solve any rubik's cube in 20 moves.

In fact, if you gave most competitive cubers the superflip (a position requiring 20 moves), they would solve it in 20 moves. I can say that this is false. While in the face turn metric(which is what the researchers were using) requires only 20 moves for the superflip, none of those optimal move pat...

One of the corners of the Morley equilateral would not be in the same center as the rest of the centers on an equilateral triangle.
