   In a Quora question about the most dense small book, the answer   
   is Rayward-Smith's "A First Course in Formal Language Theory".   
      
   I wonder if this is a well known book on Formal Language   
   Theory, and is really that dense.   
   [There's a copy in the Internet Archive.  I took a look at the   
   first chapter which is quite mathematical but no more than I   
   would expect for this material. -John]
