Ayy, I'm a big signal guy.

Check this out:

1. Paint an infinite white line
2. Paint a section of 1 inch blue on the middle
3. Every section 1 inch to either side of the blue must be painted blue as well
4. Repeat

The blue part is infinite but a smaller infinity than the lengths of white on either side.

This is called a subseqence, which is when you take elements of a set and abstract them while keeping their mode of relation identical. So, (1, 4, 7) is a subsequence of (1, 2, 3, ... 10).

This is worth understanding because herein lies the arcaum for the deciphering of any signal inside any noise.
