I've been reading a book called A Beginner's Guide to Constructing the Universe, which talks about how numbers, shapes, and specific quantities affect structure and design in the universe, and I was inspired to write about where numbers are found in the diabolo and diaboloing. I'll add to the list as it grows:

1: one diabolo, the diabolo's axle is seen as the uniting point of the two cups, the minimun number of sticks to constantly hold (infinite suicides)

2: diabolo sides, types of suns (clockwise and counterclockwise, types of trapezes (regular and inverse)

3: 2 sticks and one diabolo interacting

4: possible low diabolo limit?, 4-point vertax

5:

6: the number of trick classifications I made: grinds, knots, orbits, body movements, suicides, whips

7:

8: types of wraps, **8**-point vertax

9:

10:

I'm probably going to get complaints about the trick classifications, but they work for me.
