]]>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.
]]>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.
