Subject: [seqfan] Can more of these terms be found?



Hi all seqfans,



So far only 2 terms are known that will always, I believe, be of odd length

and one integer per discrete length.

On the first term subtract the 2 high order digits from the 3 low order 
digits.

Square the results which will give the original integer.

82369 ----369-82 =287---287^2 =82369

1201216 ---1216-120=1096---1096^2 =1201216

This was just posted on sci-math given the larger integer above.

I found the smaller one (82369) .

Is a (9),(11),(13)..  digit possible to calculate?

Dan
