Paul Chicken

Paul Poulet (* 1887 ; † 1946 ) was a Belgian amateur mathematician, known for his contributions to elementary number theory.

He introduced Sociable Numbers in 1918 (in L'Intermédiaire des Mathématiciens) and he was looking for great Perfect (and Multi-Perfect) and Friendly Numbers .

He tabulated the Fermat pseudo- prime numbers for base 2 (sometimes also called Chicken numbers) up to 100 million (1938), after tabulating them to 50 million in 1925.

In 1925 he found 43 new multi-perfect numbers, that is, numbers for which the sum of the positive factors (including the number itself) is equal (perfect numbers are the special case k = 2). Among other things, he found the first two examples for k = 8. ${\ displaystyle n}$ ${\ displaystyle k \ cdot n}$
