By the way, in Caldwell's The Prime Glossary, the entry Colbert Number needs to be updated. /JeppeSN

I wonder if Louis Helm invented the term Colbert Number? At some time around 2009, he wrote an article Colbert Number (Wayback Machine) on Weisstein's MathWorld site, and then wrote a post on seventeenorbust.com (Wayback Machine) dated 15 Apr 2009 where he says Colbert Number is an official name and later links to his article on MathWorld.

Now, the MathWorld page needs to be updated as well.

haha, yeah I think there was one with him about the record Mersenne prime where he also mentioned "the underdog" PG that caused quite an influx of new users. :)

Numberphile rules. For me it was the other way around, I stumbled across the channel after I had joined BOINC/PrimeGrid and was looking for additional info.
