M,E,S,x,y,z notation should should belong to the scrapyard!!
M=MR'
E=MU'
S=MF
x=CR
y=CU
z=CF
Nothing to memorize that way!
Sorry for bumping an old thread...:cool:
An improved 2-flip using jumbling:
UF+ FR UF FR UF FR UF++
UR FR UF UR UF FR UR (14 turns)
I am very sure this is optimal. But I have no idea how to prove it ...

That was really compact!! But it has no user input and no output formatting. My code can actually group the digits in blocks of desired size and with chosen delimiter. For better readability :D
I did not know that Python works "out of the box" with really huge numbers. Will it also do decimal...
Using the bcmath library in PHP is a lot of fun. It does maths on numbers represented as (long) strings. I made my own functions for exponeentiation and factorial to make it work :)
Hi,
Bump warning!!!!!!
I made a simple script for calculating permutations on nxnxn cubes of various sizes.
Here is an example with size=6.

Obviously you just change the size parameter in the querystring for other sizes. If the size is...
Maybe. But it's a different ball game for branded fashion like Gucci, YSL etc. If you buy fake copies when travelling you may face severe punishment upon arriving home. Who can believe you can really get a genuine Rolex for $20 anyway? Hmmm ...
In our case i consider the dayan "genuine" and...
Yes, at least the name is my invention. The method itself is not rocket science, so somebody else must have used it or someting similar before me. And btw. K4 is truly yours :rolleyes:
On the more serious side. Do seventowns sponsor any other competition than the major ones like Euro, World...
F*** seventowns!! Can i copyright my cage method or the way i shave? Utter utter stupidity and greed. They have absolutely no credibility left. Sorry seventowns. Sad to see the comapny go down this way. They once sponsored our competitions. We don't need them anymore. It's time to move on :tu

I found GT boring also at uni, mainly because there was no good real work examples to demonstrate the theory. The cube and other puzzles are great visual aids!!
Per
I second that. Especially because it is also impossible to change the old results currently in the WCA database.
On a second note let us start to record all those +2 into the database, together with the original result.
We should always record raw data and what we have done to it
Per
Another great topic for a short essay. Show that the 2x2x2 cube can always be solved with turning 3 layers only. Those 3 layers should be all-adjacent, like U-F-R or D-B-L etc. Show also that non adjacent 3 layers like U-F-D won't work (in general).
Per
Yes. My main point is that we keep all raw data. And then decide "later" how we will display those times. It can be rounding, truncating, a mix or whatever ...
Keeping all the raw data gives competition organizers one less thing to worry about. Just report back to WCA the times recorded, be it...
If we can get a way to store full 3-decimal times in db while displaying truncated times. I would be happy with that. As long as we keep all raw data. Just in case as they say ...
Per
Or why not simply round the times with the new timers according to standard rounding off rule:
12.504 => 12.50
12.505 => 12.51
Then we can preserve all the old times. The database can automatically do all the rounding off of new times. No need to do them at the competition venue :)
Per...
Actually i found a short solution myself:
1. DFR- DFL+ DFR+ DFL+
2. DFL- DFR+ DFL+ DFR-
This shortens to a mere 5 turns:
3. DFR- DFL+ DFR- DFL+ DFR-
This sequence can be repeated in several ways for various patterns.
For the mirror solved state we can do:
4. UBR- UBL+ UBR- UBL+ UBR-...
Hi!
Since the dino cube has neither facecenters nor 3-color corners - there are 2 possible solutions to the puzzle. 2 opposite faces can "change" by performing 4 piece swaps, involving 8 of the total 12 pieces. But i do not know of a short way to go from one solved state to the other. Can...
As the poster said later:
Russell Heimlich responded on February 9th, 2011:
Ha, you’re right! I never noticed that. I wish the CSS spec was more specific about border styles. They can be all over the place across browsers.
I guess it works in most browsers. I haven't tried.
