I don't think any source has done that for
Sphenic numbers or mentioned the possibility so I don't think we should do it either. It's not common to do it for other sets than prime numbers. If we do it then it may seem like it should have some special significance for sphenic numbers but that is close

it makes sense to me to have information about why notable alumni are notable but I wouldn't expect information completely unrelated to being an alumni listed, such as how many children they had, or where they were born. Information like that should be in the article about the person, and I feel the

I object to Ams80 calling mathematical facts such as
Catalan numbers and pentagonality "pointless trivia"; facts such as these are extremely relevant to articles about numbers. But I don't object to Ams80 removing those facts from this page, since those facts at least are stated in the pages on the

I changed the part " ...because one of every four consecutive integers is divisible by 4..." to "...because one of every four consecutive integers (except the numbers ranging from -3 up to 3) is divisible by 4..." simply because the statement was incorrect, though I don't like this solution, can

Is it quite right to say "Currently, the largest known sphenic number is i.e., the product of the three largest known
Mersenne primes"? Would it not be better to say simply "Currently, the largest known sphenic number is i.e., the product of the three largest known primes" adding, if required

distinct factors". Also if these are the only factors, we should say so as the article then implies they are: It says there are 8 factors of a sphenic number and then lists them. The definition is ambiguous. Anyway, I've "fixed" it and I hope it is correct!
377:. This seems a better solution to me. Sphenic numbers are defined as positive integers in the opening line. Limiting the argument to positive integers avoids an irrelevant discussion about negative numbers and the status of 0.

Maybe I should clarify, I didn't mean to say, and don't believe, that concepts such as
Catalan numbers and pentagonality are "pointless trivia". What I meant to say was that, for example, the fact that 105 is

I am formulating the definition to simply say "the product of three distinct prime numbers". I think this is short and clear. If anyone is in doubt anyway, the next sentence says squares are not allowed.

I find it hard to believe they were copying wikipedia back in 1964, as that would create a timelike-loop somewhere along the road; but still where *they* got the term is very curious, if not odd... --

same way about the numbers in this article, trivia unrelated to number x being a sphenic number should be in the article about number x (if anywhere). Just my opinions --
