摘要
In 1638, Descartes showed that 3(2) . 7(2) . 11(2) . 13(2) . 22021(1) would be an odd perfect number if 22021 were prime. We give a formal definition for such "spoof" odd perfect numbers, and construct an algorithm to find all such integers with a given number of distinct quasi-prime factors. We show that Descartes' example is the only spoof with less than seven such factors.
