How to define if a number sequence is easy to remember or not?
I'd something in mind for a few days that how we can determine a number sequence is easy to remember **through code**?

Is there anybody that has information about this.
I tried searching for algorithms and psychological papers that define the relations with our minds and the numbers.

I had found psychological research papers (like [this][1]), but I need to know if there's a known or related algorithm that can help me define these number sequences are easy to remember.

Thanks in advance.
Any help will be appreciated.
