> In binary you need to make 53 pieces, in ternary 50, in octal 69 pieces, in decimal 81 and in hexadecimal 101. These numbers don't quite make sense to me. Hexadecimal should have 16 symbols, and then `log16(whatever) = message length`. I get what you're trying to say though. That trend continues up until the symbols start looking the same and no one can read them, and now the most important problem is not a position on a tradeoff curve. It's that the system is no longer reliable. If you wanted each letter to have the highest probability of successfully being read, you would use a grid, and shade or leave blank each grid square.
