Loved your Langford Pairing blog post. Found a small error in the proof of sufficiency. I think the value of \( c \) should be \( 4x - 1 \) and not \( 4x - 3 . \) Great blog post though!

Wonderful Langford Pairing post. By the way, I believe there is a small typo in the formula for \( c. \) It should be \( c = 4x - 1. \)

Thank you, Ikiatl and Presh, for your comments. The formula for \( c \) indeed had a typo. Although I wrote the correct values for \( c \) obtained from the formula \( c = 4x - 1 \) in the examples, the formula itself was written incorrectly as \( c = 4x - 3. \) I have corrected Langford Pairing to use \( c = 4x - 1 \) now.

Read Nested Code Fences in Markdown. Nice post! One tiny correction in this sentence:
So when we put Becky within a code span, the first backtick in Corey's face would terminate the code span immediately and then the rest of Becky would lie outside it.
I think that "Corey" should instead be "Becky".

Dan, Thank you for the correction. Yes, that should indeed be 'Becky'. I have made the correction now.

Hi Susam. A small correction in
Emacs Info Expressions.
The prefix to copy the info expression is C-u 0 c,
not C-0 c.
Also, news.ycombinator.com/item?id=40021782 links to emacs-info-expressions.html (note the "s" in "expressions"), which doesn't exist now (not sure if a bug or intentional rename).

Hi Mario! The key sequences C-u 0 c and C-0
c are equivalent in GUI Emacs. If C-0 does not
work for you, then you are likely running Emacs in a terminal. Most
terminals do not recognise C-0 as a key combination.
In a terminal, you should type C-u 0 c, as you
mentioned, or alternatively M-0 c. I have updated the
article Emacs Info
Expressions to include this detail.
About the article URL, you are right. I had inadvertently renamed the article file. I have now fixed it and the article is now available at emacs-info-expressions.html again. Thank you for reporting this issue.
