6. Conditional Structures

   • free forehead, brow locked together-to-buzzer, no-together-to-buzzer, left-free, left-blocked, some-buzzer-in-a-bag, no-buzzer-in-the-bag, right-free, right-locked, geared-to-north facing-the-south non-oriented-to-north, non-targeted-to-south, non-oriented-to-east, and non-geared-to west.

7. Repeating Structures
