## Main Question or Discussion Point

A pattern that does not continually re-occur?

I'm not sure I understand what you mean. What kind of pattern are you talking about?

A finite one. A pattern in which you relate one thing to another. It stops there. Basically, can you distinguish that a pattern exists with only 2 symbols?

I'm not being smart, thats just the only way I know how to put it.

Thanks for trying though.

Does that count?

Is a pattern a signal that can be generated using an algorithm?

i dont think a pattern can be established with only two symbols by definition of a pattern.

For example, given two points on a missile trajectory can you predict the third point. You'd have to assume a line but the missile would most likely be on an arc so given a third point gives you enough info to predict the fourth and beyond with ever greater precision.

Now in statistics, they often look for correlations between two variables and that is a kind of pattern.

where the "pattern" is that the number of "0" between two "1"s is one more than previously.
