Eleventy is an infinite string of ones.

Eleventy is not infinity as it is quantifiable. Like pi, eleventy is calculable to an infinite place. By knowing how to calculate eleventy, it makes it a uniquely simple infinite number sequence. The main difference between infinity and eleventy is that we know exactly how to begin and end writing eleventy. Eleventy, in similarity to pi, is quantifiable.

The number eleventy is divisible to a whole number by every single number that exists in any numerical place in the string, which makes it unique from many other numbers.
eleventy to ten places = ...1111111111

To begin calculating eleventy, you start with one and add the exponential of ten to the power of 0. From there on, you add the exponential of ten (starting with one), never using the same exponential of ten.

1+(10^0)+(10^1)+(10^2)+(10^3)+(10^4)...
(or)
1+10+100+1000+10000+100000...

You repeat these steps until time ends. That is eleventy.
