Why 2358?

The number 2358 isn't random. I chose 2358 because 2,3,5,8 are Fibonacci numbers. This is clearer when we write 0, 1, 1, 2, 3, 5, 8. Notice that each number is the sum of the two previous. So the next numbers in the sequence are 13, 21, 34, 55.

I choose the Fibonacci numbers because their important in my math research. They appear as the dimensions of a graded ring that is of great importance, at least to me. They appear in many other parts of mathematics (see the OEIS link below).

The ratio between one term and the next converges to the Golden Ratio. It's important in classical Greek art and architecture. For example Live Science (URL below) writes

Phidias (500–432 B.C.) was a Greek sculptor and mathematician who is thought to have applied phi to the design of sculptures for the Parthenon. Plato (428–347 B.C.) considered the Golden ratio to be the most universally binding of mathematical relationships.
