More information is needed!
The article begins as follows:

"In mathematics, Catalan's constant $G$, which appears in combinatorics ..."

But the article contains no explanation of any connection with combinatorics.

I hope someone knowledgeable about this connection can add this information to the article. 2601:200:C000:1A0:54DF:44B8:50C7:FD7E (talk) 18:03, 14 April 2021 (UTC)
 * I suspect that this is the connection to domino tiling. I just added something about this to the article but it could probably be expanded. —David Eppstein (talk) 20:12, 14 April 2021 (UTC)
