According to Wikipedia,

A Sphenic number is a positive integer which >is the product of three distinct prime
numbers.

Anybody knows whether there is a list, say first 1000 sphenic numbers? It would be much helpful to know.

Thanks in advance

I edited the title question. (The answer to your previous question is, quite clearly, "infinitely many.") – Qiaochu Yuan Oct 4 '10 at 8:26
Does it mean that the set of sphenic numbers is infinite? Since, prime numbers are infinite it is understandable. But, I hear the further go to the positive X-axis the fewer you get primes. So, the set of shpenic numbers at hand might be finite? – Sazzad Bin Kamal Oct 4 '10 at 9:32

To get a sphenic number, you just take any three distinct primes (and there are clearly infinitely many ways of choosing three primes!) and multiply them. – Hans Lundmark Oct 4 '10 at 11:33
Thanks. But, isn't it just n*(n-1)*(n-2), where n is the number of distinct primes? – Sazzad Bin Kamal Oct 4 '10 at 13:37
@Sazzad, you should really explain the term "sphenic" (or any other uncommon term you are using) before using it :-) – Srivatsan Sep 8 '11 at 16:15

The first 10000 are listed here. (Found via Wikipedia: Sphenic number and OEIS.)
