### Julianthemath's number

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.

### Re: Julianthemath's number

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

### Re: Julianthemath's number

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.
