Title: On the integers which are the totient of a product of two primes. (In English)
Source: Q. J. Math., Oxf. Ser. 7, 227-229 (1936).
Review: The author proves, by a method very similar to that used in a former paper (Zbl 013.39003), that, for an infinity of values of n, the number of solutions of the equation n = (p-1) (q-1), where p and q are primes, is greater than \exp{\sqrt{(log n)-\epsilon}}.
