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 ... Per : D

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. http://fmc.mustcube.net/Cube_Permutations.php?size=6 Obviously you just change the size parameter in the querystring for other sizes. If the size is...

Dudes! Do it with feet like a shimpanzee (correct spelling?). And please standardize the banana size (length and/or weight!) Per

Nah, they are too busy trying to "reinvent the wheel". New useless non-twisty puzzles. Marketed as the "bew rubik's cube". Yeah, right!! Per

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 Per

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
