Sprite. The two types of unique rectangles that I see are these. Type one:
(3, 6) (3, 6)

Ooops, mistake. Must hold down shift key. Type one:

Rats did it again.
Type one:
(3, 6) (3, 6)
(3, 6) ( , ) the last is neither 3 nor 6.

type two:
(3, 6) (3, 6)
(3, ) (3, ) neither of the blank spaces can be 6.

There is also the bent unique rectangle:
(3,6) (3,6)
(3,6) ( , ) ...... (3,6)
( , ) (3,6).........( , ) Neither of the last two blanks can be 3 nor 6.

I hope you can understand the notation.
Just once I encountered a unique trident -- same principle as a unique rectangle but triple wide and triple long if I remember.

And a bent unique rectangle could have two bends, something like a Z. But I've never seen one.
