Arrange two of each digit (0-9) into a 20 digit long number, which does not begin with a zero, then score your number as follows:
For every 2 digit sequence that forms a perfect square score 2 points, for every 3 digit sequence that forms a perfect square score 3 points. A four digit square would score 4 points, and so on.
For example, if your number was 58738219024971503664, then you would score 2 points each for 49, 36, and 64 and 6 points for 219024 giving a total of 12 points. You may not count 036 as a three digit square.
What is the maximum number of points you can score?
