What are those magic symbols?

Question

Having found a nice vector graphics for magic symbols, I wonder what the symbols on the second-to-last row are. I recognize tap, untap, infinite and half, and the last one as the earlier white, but what are the others?

Answer 1

They are old versions of the tap symbol.

As it is explained in this article posted on Daily MTG, the symbol with the T is the tap symbol from Revised through Fallen Empires and the one with the rectangle is the tap symbol from 4th Edition through Scourge.
