The proof known to Euclid of the infinitude of primes is well known. I would like to know which book of Paulo Ribenboim's was being alluded to in the comments section of my previous post [1].
In addition to the aforementioned book, are there similar such compendiums with regards to the subject of this post? One such is on the Wiki [2].
