I can't tell from the images on:
if the edge you can't see matters for step 4a.
I also find this step to be tedious and frustrating most of the time, does anyone have any tips?
Here you can find algorithms to solve many different situations on the cube. If you have an algorithm you want to add, simply click on the link, and click on "Edit" at the top of the page, find the according case, and add it. Be sure to follow the syntax of the page before adding an algorithm...
At the point i am at now i guess it be about time to learn OLL, however theres 57 of them, i already know about 18 from PLLs and some memorization here and there.
Now i want to learn the rest of them, right now i have notecards layed out with the pattern on one side and the alg on the back...
