-40th term has 63138 digits
-Out of curiosity, I wrote this dirty C++ proggie to generate a few, http://pastebin.com/f5e20941b (I've used VisualStudio 2008; it displays in the following order: [iteration].[number of digits in the term].[the term itself] and it needs as a parameter the number of the term to generate)
-@Secret Squïrrel: I reckon the 97th is going to be quite big
