God's number for Cross after EO?

[CubeWizard23]

Obviously cross can always be solved in 8 moves or less. I'm curious if EO reduces that? Couldn't find anything on the wiki specifically addressing this. Currently experimenting with EOcross in my casual solves.

I think it is 4 moves atmost, I have not verified this.

I may be wrong yo

It's at least five because you could have all four edges in the u layer misoriented by a quarter turn. ie: R2 F2 L2 B2 U

is this assuming EO has to be preserved or not ?

Preserved. A cross preserving EO should be as fast if not faster than one destroying EO if EO is already solved.

Here's one that needs 6 moves: L' R' B2 U' L' D.

it still should be 8 or less. The avg when cross is solved already is 5-6 moves

i think you made a typo cause if the cross is solved then it takes 0 moves to solve the cross.

did u mean EO ?

Assuming white on top and that as the scramble you could solve it with:
L2 U' R' U2 R2 right?

 

[Olicube4life]

And what about R'U R'U R'U R' isn't that 7?
Or does someone have a better solution?

U2 R2

edit - thought this was cross on bottom

I was referring to the cross on bottom, so yellow if you scramble with white on top.

And what about R'U R'U R'U R' isn't that 7?

Yeah, that's a 7-mover for cross on top. Nice one!

I think 7 is the upper bound because you could bring every edge piece to your cross with one move and you need one move to turn your cross so it is in the right position in relation to the other edges but the first one doesn't need that move. But you have to align the cross right so that will be eight? No because you could always insert not all pieces need that move to align the cross with itself except for when the pieces are all in the same layer(R or L) but then the first piece is already inserted

So that means with the lower bound also being 7 that gods number for cross with EO needs to be 7

Let me know if I'm wrong

There are 8 movers.

Ex: F R' F' B' R2 U B R

 

[Olicube4life]

There are 8 movers.

Ex: F R' F' B' R2 U B R

But in your case your cross edges are not EO

 

[That0newe1rdo]

There are 8 movers.

Ex: F R' F' B' R2 U B R

is it me or does your example not even scramble the cross, just ruins EO.

did you think OP meant whats Gods number for Cross + EO ?

R' B2 L D...

 

[Olicube4life]

R' B2 L D...

Crazy bump but I think he was referring to cross at the bottom because that has a six move optimal solution

Yeah. If anyone is curious I calculated all EOCross scenarios and it is 10 for fixed cross.

Do you mean cross + EO?
