I would also recommend the following two puzzles in this category:
(a) The puzzled titled &quot; Counting Problem&quot; created by Acolyte { which was about finding a bijection ( one to one mapping) between the set I of integers and the set Q of rationals}.
(b) The &quot; Puzzle of syntax -why only one...&quot; created by rspoddar82, which was about filling in the blanks of a sentence with numbers written in words so as to make the two sentences correct. The second part of that puzzle is as yet unsolved. I had submitted a mathematically correct solution to the second part, but that was dubbed as wrong due to grammatical &amp; syntactical reasons. It was stipulated that the sentence must be both mathematically and grammatically correct.

&quot;Triangle Puzzle&quot; posted by THUD and BLUNDER was also a challenging and beautiful one.
