Saint Augustine (among others, including the early Hebrews) considered 6 to be a truly perfect number—God fashioned the Earth in precisely this many days (rather than at once) to signify the perfection of His work. Indeed, as recorded by Alcuin of York (who lived from 732 to 804 c.e.), the second origin was imperfect, as it arose from the deficient number 8 > 1+2+4, this number counting the 8 souls in Noah’s ark (Noah, his three sons, and their four wives, in Genesis, chapter 7) from which sprung the entire human race [8]. Philo Judeus, in the first century c.e., called 6 the most productive of all numbers, being the smallest perfect number. Throughout the centuries that followed, various mathematicians carefully studied perfect numbers (see the continued extensive history given by Dickson [6] and also by Picutti [14]). Up to the time of Descartes and Fermat, a sizeable pool of important results—as well as much misinformation—had been collected.
