21-letter (usually) seriation was used to make both digraph frequency
analysis and transparency analysis harder.
According to the German WWII documentation 17-letters per two lines,
a blank line and then again 17-letters per two lines and so on.
There were variations, but the Army and most others used 21 letters. I don't know what the blank lines were.
