Once you think about 26...

...you'll start seeing it everywhere. (You can thank me later.)

Levi found this in Donald E. Westlake's The Hot Rock:

"The number 26 lit over the door, and the elevator came to a stop."

And Dizzyhead Bill writes in:

Your request for 26 significa led me to the WikiPedia page for 26. The two highlights, for me:

Scoring 26, by hitting 20, 50, and 1, is a "joke throw" in darts that "usually results in sneers or laughter from the audience."

A Rubik's Cube can always be solved in 26 moves or less.

How numinous is that?
