Hi everyone,
In response to the posts mentioning the 300 move mark for the 3^4, I felt I=
should update that information, I have been sitting on this for too long a=
nyway. At the end of November last year I finished trying to beat Roice's =
298 twist record. End of story? Not quite. When I reached the start of t=
he last stage of the solve I thought I had already done enough to claim the=
title and spent little time optimising the last stage. Record sitting at =
282 twists so far, but I wasn't finished. However motivation started to sl=
ip a little at this point and I only spent a little bit of time here and th=
ere working on the solution.
One day out of nowhere I decided to tackle it again. The last step of the =
solve is effectively a 3x3x3, so I worked on the solution on the train and =
found a good solution on the return journey from university (first year exa=
ms soon!), maybe 33 moves but I'm not sure on that. Transferred that solut=
ion into MC4D, and with a bit of effort, knocked the move count down to 251=
. End of. Er ... no actually. Our old friend parity paid a visit at the =
end, adding around 20 moves to the solution (I believe this particular pari=
ty has been mentioned here by Klaus and I posted a solution). That was the=
story at the end of February, and motivation had disappeared for a while. =
I have a funny feeling I know what I'll be doing tomorrow though ...
As they say, watch this space.
Matthew
I can confirm that Matthew has indeed submitted a 251 twist solution
today. If anyone else is sitting on a shorter solution I encourage you
to dust it off and send it in. Also, if you think you might be able to
break that record, I suggest that you do it soon so that you can hold
the record for a little while at least. Even when it is in tern broken,
it will still live on in Remi's Hall-of-Shortests

Congratulations Matthew! You may know what you'll be doing tomorrow, but
I can also guess what Roice might do too. :-)

Great job Matthew!
I've looked on your solution: awesome start and later handling of the
solved parts.
Updated: http://www.ift.uni.wroc.pl/~rdurka/rubik/hallofshortest/
Please correct me if I'm wrong:
People who broke 500 twists barrier on 3^4:
-Mattew Sheerin, Roice Nelson, Audrey Astrelin, Klaus Weidinger, me and
I believe there was somebody else
People who broke 400 twists barrier on 3^4:
-Mattew, Roice, Remi
251 barier is damn low... I think Roice has reached limit of his method
(so am I) but now Matthew provided a proof of new method so we will
see how much we can learn from it :)
Roice if you want to try a new record from the very beginning I propose
to use Matthew's scramble. That will be fun to see how much close we can
be in distinct solutions.
All the best,
R
