(...) Hmm... What if you did it with a 40 and 20? The spacing would be... wierd... 3 1/4 studs or something? You'd have to do it vertically, I guess, to get half of a half. (21 years ago, 2-Jan-04, to lugnet.org.ca.rtltoronto)

(...) Works well with 3 bricks vertical offset, 1 stud horizontal. There is also 12 + 24, but that suffers from a similar problem.
