You can do super dense mathematical code in the ancient APL programming language[1]. I wonder how even more tiny this program could get at the hands of an APL expert if any still exist. Here are some complete APL programs[2] to give a flavor of just how dense it can get: Sum integers from 1 to 100: +/ι100 Find all primes from 2 to a given number R: (∼R∈R◦.×R)/R←1↓ιR Play Conway's Game of Life: life←{↑1 ⍵∨.∧3 4=+/,¯1 0 1∘.⊖¯1 0 1∘.⌽⊂⍵} [1] https://en.wikipedia.org/wiki/APL_%28programming_language%29 https://en.wikipedia.org/wiki/APL_%28programming_language%29 [2] http://www.vaxman.de/publications/apl_slides.pdf http://www.vaxman.de/publications/apl_slides.pdf
