Forgive me for asking a question that is only indirectly related to higher dimensional cubing. I'm sure many of you can give me an authoritative answer. The...
Guy, Anything even remotely related to 4D cubing is fair game on this list so don't worry about that. Your question is very interesting and appropriate. It...
Thank you very much for your answer, Melinda. The motion parallax point is interesting but yes, it is cheating as far as answering my real question is...
Guy, When you talk about animals and predator/prey strategies, you are talking about real-world situations and not purely geometric ones, and the difference is...
How many legs would a 4D creature need to walk on a 4D planet. On a 3D world an object neads at least three legs to stand stably. Would that mean that in order...
I don't know about you but I'm able to stand upright in 3 dimensions with only 2 legs. ;-) Seriously though I think you are right that N legs are required to...
Hello everyone,  I just wanted to let everyone know that I have finished counting an upper bound for the number of permutations of an nxnxnxn Rubik's Cube,...
Hello to all of you. I'm Thibaut Kirchner, nearly 21 years old, and live near Paris, France. I'm student in maths and computer science (fifth year after in ...
... required to solve ... question would have a ... less confident I can ... I suggest you to explore the following groups, and their successive quotients...
Hi Thibaut,  Welcome to the 4D_Cubing group! Congratulations on solving the 3^4 cube! I also do speedcubing, but my times are probably not close to yours -...
... Well, if you give a look in the WCA database, you'll see my times at Brussels Summer Open: I averaged at 57 s, which is in fact quite close to your times. ...
Hello! I haven't read the old messages, therefore I don't know if this has already been suggested, and apologize in advance if this is the case, but here is my...
Wow... I never considered that my times would be tournament-worthy! I use a 2-look F2L and a 4-look LL! I could definitely get faster by learning F2L and ...
... In fact, in 3D, we can also switch two corners, but this is the same as switching to edges, since a quarter-turn of a face transfers one parity error on...
Hi Thibaut, Welcome! There are a lot of topics floating around (thanks for the parity writeup by the way), but here I'm only replying about your desire to...
Roice, You already implemented the show-the-cubie-that-goes-here functionality, right? In other words, the compliment to the show-me-where-this-cubie-belongs...
Thibaut, That's a very good suggestion. It wouldn't be a trivial change because we want to support more puzzle types and therefore this sort of feature belongs...
Hi Lucas, Sorry for the very long delay in responding to this. I didn't want to leave the possible issues you raised unresolved in the thread, but hadn't...
Yep, shift+ctrl+clicking does the piece finding functionality, and left/right clicking distinguishes between the two complementary cases you mention... Roice...
Hello all of my 4D friends :) It's about time I got back to this crazy obsession of mine! I was devastated by Remi's improvement on my 3^4 checkerboard...
Yeah, I know the feeling of no one caring. Well congrats on finding a new record. The only thing that's going to be disappointing is when we actually do find...
Hello Mark! I'll start by saying someting funny: Today again I got the proof that I have some special gift. From nowhere I just typed link to my page with the...
Dear Remi (et all), So I guess it's time to have a history of the checkerboard solutions added to your hallofshort.html! What a freak coincidence! The actual...
Hi everyone,  First of all, nice to meet you, Mark and Remi, and congratulations to both of you on your checkerboard solutions! I thought I would update...
... I'm amazed by the complexity of the formula. I suggest you to split it into two formulas, one for the odd-sized hypercubes, and on for the even-sized...
Hi Thibaut,  Thanks for your comments and suggestions! I put a lot of thought into what you recommended to me about the formulas, but I have decided to...
Can I ask about formula as the input for program Mathematica (or Maxima, etc)... Or just see actual numbers for any hypercube we have? all teh best, RemiQ ... ...
Hi Remi,  I have written two functions for GAP (It's the main computer algebra system I use) for you which compute the number of permutations of an n^4...
