HUGE cross Challenge.

[Derrick Eide17]

Alright everyone, so i got challenged by one of my friends that i couldnt solve the cross for a scramble in under 7 moves so i accepted and omg did i get myself into some trouble. i just couldnt do it! i got 7 move cross over like 5 times but just COULD NOT get 6. and i even try Acube after that and it kept screwing up so i couldnt do it. Lets see if ANYONE on here can. using half turn metrics of course.

Scramble with cross colour on bottom.

Scramble: LRD'BFRD'F'



Good Luck!

Mabey it isnt possible. But i havnt tried it yet ill post my results.

 

[Derrick Eide17]

Yeah i started thinking it isnt possible as well, all crosses are supposed to be possible under 7 moves but i dont think that counts as half turn metrics too. im sure its possible using other metrics but try only half turn metrics. so M equals 2 moves causes its basically like L R'.

I'm not really sure what you mean, but all cross are possible in under 9 moves, not 7.
And if you wanna solve the cross for D on this scramble, there isn't a solution for under 7 moves.

x2 B' R' L' F' = 6

umm... a couple of things andrew. First off, he said cross on bottom. Second, you're notation is wrong. You did a x2 instead of an z2...

Shows the advantage of being color neutral. :-/

This is one of the cases that's impossible to do. haha. 98%(I think) of all the crosses can be solved in 7 moves OR less.

Actually, I think it's 99.95% of the time. The remaining .05% of the cases take 8 moves.

 

[hdskull]

Oh okay, I was close, haha.

this is in fact possible, there are two different solutions for this one. you guys would know that if you had read the previous post by exocorsair where he posted this link: http://funktio.awardspace.com/misc/cross/index.pl which is a cross solver. go ahead. try it.

Obviously, you haven't tried it or read the post clearly. It says UNDER 7 moves on D, and there are no solutions.

and i even try Acube after that and it kept screwing up so i couldnt do it.

Enter a cube configuration:
UF UR UB UL DF DR DB DL FR FL BR BL UFR URB UBL ULF DRF DFL DLB DBR
BD @? @? @? @? LD DF RD @?? @??

[snip]

depth 5...
depth 6...
depth 7...
F R' B' D' B D2 R (8q, 7f*, 7s)
F' L B D B' D2 L' (8q, 7f*, 7s)
Done. (2 solutions found)

lol, this is hard for me to even attempt because I like to do a lot of preserving so when I see the c/e pair and all the other stuff that is connected I want to preserve them instead of ignore them just to solve the cross which means I would probably get 10 moves on this.

But anyway, as we can see, it is impossible to do in under 6 moves so it isn't really a fair challenge.
