To get a Julianthemath number, follow the text below this :

All Julianthemath numbers are the sum of 2 consecutive square numbers.

Example :

1 + 4 = 5 - A Julianthemath number

4 + 9 = 13

So, Julianthemath number * Julianthemath number = Julianthemath square

So, 5 * 13 = 65 - A Julianthemath square

If you play "Add 1, then post a fact.", include this.

Hi julianthemath;

Nice sequence, look at A001844 in the OEIS. These are also centered square numbers. I'm sure that in "Add 1, then post a fact" I will include julianmath numbers

Then julianthemath squares can be obtained with 4n^4 + 1.

Sorry Julianthemath, but in the OEIS there are 200000 sequences, I sent to them 40 sequences and they accepted just 10.

Sorry becuase your sequence is in the OEIS. It is never nice when you find something that someone else has already discovered.

Oh. I didn't know that at first. But, is there a OEIS square and OEIS number?

OEIS stands for Online Encyclopedia of Integer Sequences. It is a collection of number sequences.
