| Thanks! I've never seen these before, but I was wondering if there were any that fit this pattern, so I wrote a program to find them.
Since then I submitted several series to the Online Encyclopedia of Integer Sequences (OEIS) about these numbers. (See http:// www.research.att.com/ ~njas/sequences/A153745.) |

| Very interesting but you surely aren't expecting us to get all of those properties without looking at the answer , are you? :roll: |

| I agree this is more of a puzzle than a teaser, but I think it's possible to get the answer. If you observe that the numbers are all squares and that their digital sums are all squares, I think it's possible to get the next step with the sum of the digit pairs. :) |
