From: Allan Wechsler To: C.McCaig@queens-belfast.ac.uk Cc: cube-lovers@ai.mit.edu Subject: 4x4x4 solution [C. McCaig:] i recently borrowed a friends 4x4x4, and i know the basic method for solving it. ie get the 6 centres, pair up all the edges, and then solve for the normal cube. however, about half the time i end up with a single edge pair inverted and cant figure out a move for reorientating the single edge pair. usually i break a few pairs and try and reorientate them this way, but this seems rather longwinded... does anyone have a move for this?. for example, say the green edge is on the blue face, and the blue edge is on the green face... What's happened here is that you've got those two edge-cubies _exchanged_. Here's how it works. Look at any face. You will see eight edge stickers, arranged around the face like eight square dancers (or Irish set dancers, if you prefer). Now I hope you are familiar with one or the other of these kinds of folk-dancing, because otherwise what I am going to say won't make sense. Those eight decals are either men or women, and no matter how they dance around the cube, they will never change sex. Every edge-cubie on the 444 has one permanently male and one permanently female sticker. If I haven't clarified things, at least I've spiced them up a bit. House around to home. - -A ------------------------------ Date: Tue, 30 Sep 1997 14:18:17 -0400 (Eastern Daylight Time)
