I was in the WCA chat, and i was asking for some advice on fridrich, and someone said something about 10 core OLL algorithms that i can use instead of the 57 different OLL cases normally used, does anyone have any information on this, because 10 sounds a lot simpler than 57, even if it will raise my time by a bit.

Possiby they meant for a 2-look OLL? Like 3 algs for edges, then 6 for corners? but that's only 9, so idk what the 10th oen would be.

7, actually

AndrewG, the other Sune.

chris, the edge orientation algs, too.

As Swordsman Kirby was saying, there are also the edge-orientation algs. Here are the ones I use:

4 Edge Orientation (None) - M U R U R' U' M2 U R U' r'
4 Edge Orientation (Adjacent) - F U R U' R' F'
4 Edge Orientation (Opposite) - F R U R' U' F'

The last two algorithms are executed with correct edges in either left/right positions or left/top positions. So the basic idea is, first use the edge ones to orient the edges, then use the 7 corner ones to orient the corners. In other words OLL is done in two steps. Using these 10 OLLs I think it doesn't add more than 1.5 seconds to my time so I'm satisfied with that.

Notice which post mine follows. I am well aware of the number of cases. I was pointing out the error, not acting as an algorithm finding service.

Oh, sorry, I guess I didn't make it clear. The only reason I quoted you was so that all the algs would be in one post. I then posted mine just because I had them handy. I didn't mean for it to be anything at all against you! Sorry for the misunderstanding

I don't use the first one; the case can be avoided with a different last F2L pair insertion.

Also, I think corner orientation can be done purely with Sunes and Antisunes.

Just a quick fix.

It is very possible to average into the teens with just the 10 OLL algorithms, I think I heard of someone getting sub15 with it, which again is very possible.

After a while, you start to recognise what corner OLL you will get after EO, so the EO adds about 1 second onto your time.

Cheers for that Johannes, I am still not used to using a touch pad for moving the cursor..

Sounds kinda funny when the quote is broken.

I finally learned 1 look OLL, and it cut at least 4 seconds from my average (28->24).

I haven't learned all 57, I skipped the 8 that have all 4 edges bad. Like ExoCorsair said, I'll put the last CE pair in differently if I see 4 bad edges coming, that way I get a much easier and shorter (most of the time) 2 bad edge OLL.

Anyway the 57 seemed really intimidating to me too at first. After looking at them, I already knew about 1/3 of them and most of them are just 2 layer Sune or combinations of corner and edge orient algs with some of the "overlap" turns removed.

I had fun learning them and it wasn't as hard as I thought it would be. Not only that I'm faster than I've ever been (please be kind).

Demon Parasite, don't let that 57 scare you away.
