Are there infinitely many Lucas-Carmichael numbers? Is there an approximate formula for the number of Lucas-Carmichael numbers less than a given number N?

[edit] Number of prime factors?
The article quotes examples of Lucas-Carmichael numbers with 3, 4 and 5 factors. I think there can't be just 2 factors. Can there be arbitrarily many?
[edit] Formula for these numbers?
Is there any formula or procedure for calculating these numbers?

[edit] Named after?
That would be Robert Daniel Carmichael and ... ?? Stumps 09:29, 24 November 2006 (UTC)

So What?
This is an encyclopedia not a dictionary - therefore IMO somebody has to say if these things have any use or if it is just an acadamic novelty. —Preceding unsigned comment added by 62.25.96.244 (talk) 11:27, 27 November 2007 (UTC)
[edit] not a stub.
i guess this article is not a stub anymore: the definition is detailed enough and examples are given as well. —Preceding unsigned comment added by Halloleo (talk • contribs) 01:44, 11 March 2009 (UTC)
