I am still happy with studying polygonal numbers and representations of numbers as $n$ $n-$gonal numbers. I understand Langrange's proof of the four square theorem.
I did a Google search related to square representations and came across this JSTOR page. It is a 7 page PDF but downloading it would have cost me $12.--. The Open University Library Services came to the rescue. I searched within the category of mathematics for all documents with the title 'On the partition of numbers into squares'. This query returned zero results. A search for that same title in the JSTOR collection however did return a result. I could access the document for no charge at the OU Library.
I find it encouraging that I can read and understand this number theory article. ( From the American Mathematical Monthly, 1948 ).
