In that particular case, we form uppercase g, uppercase G, and we form uppercase T, lowercase T, so we have the purple T, this square here, we have this combining with this. So we have uppercase g, uppercase g, lower case T, lowercase T. Now let's move on to the square. We have this gammy can also combine with this gammy. So we have uppercase g, lower case G, and we can have uppercase T, so uppercase T always comes first and lowercase T comes second. Now in this square we have uppercase g, lower case g, so we have uppercase g, lower case G, and then we have lowercase T, lowercase T, so lowercase T, lowercase T. Now the next possibility is this and this. So uppercase, the letter dominant one always comes first.
