|Once someone discovers an interesting pattern or type of behavior, those particular numbers are likely to earn a collective name. So we have perfect numbers, amicable numbers, lucky numbers, Mersenne numbers, Fermat numbers, Fibonacci numbers, Keith numbers, Niven numbers, Carmichael numbers, Stirling numbers, Catalan numbers, Ruth-Aaron numbers, Rhonda numbers, and so on... One such curiosity came about in 1982 as the result of a telephone call... the birth of Smith numbers, named for the mathematician mathematician Albert Wilansky's brother-in-law.|
