Wouldn't it be slightly simpler to use a prime number of rows and columns?

  Slightly, yes! The Arecibo message was 73×23 bits, with the hope that the aliens would break lines after 23 bits. But, i f . t h e s n e i l a . e s . l i k e . o r t s u o b p h e d o n . w . r e d r o e . a r e . k c s . a d n i r e w e d . o a . e h t . n r e c i b o . e g a s s e m . a n y w a y and that's to say nothing of spiraling orders etc.

    I like 'conventional' order, and I could figure out your message block. Give the aliens some credit, they might figure it out.
