What is Bernard Frénicle de Bessy?
'''Bernard Frénicle de Bessy''' (about 1605–1675), was a [[France|French]] [[mathematician]]. He was born in [[Paris]]. He wrote many papers about [[mathematics]], [[number theory]] and [[combinatorics]]. The Frénicle standard form, a standard representation of [[magic square]]s, is named after him. He solved many problems created by [[Fermat]]. He also discovered a [[taxicab number]] and in 1693, he described all 880 essentially different normal magic squares of order 4. Like [[Fermat]], Frénicle was an [[amateur]] mathematician, but he wrote letters to famous people such as [[Descartes]], [[Christiaan Huygens]], [[Mersenne]] and also Fermat, who was his friend. He is mainly remembered for his discoveries about number theory. ==Other websites== *{{MacTutor Biography|id=Frenicle_de_Bessy}} {{DEFAULTSORT:Frenicle, Bernard}} [[Category:1600s births]] [[Category:1675 deaths]] [[Category:Scientists from Paris]] [[Category:French number theorists]] {{bio-stub}}
