Can someone show me the sprites for the Space Invaders hack?

I've been trying to draw the arcade Space Invaders sprites in an 8x8 grid and I can't seem to do it. How are the invader sprites drawn in this hack? Are they 8x8? The way I am mapping them out it seems to me that the arcade invaders in the middle two rows would have to be 11 pixels wide. Are they drawn using some sort of mirror image technique where only the left or right half is drawn and is mirrored to produce a complete invader?
