Subject: Re: [MC4D] Minimal number of pieces affected via a slice move in n-dimensions

I think that is a different move than Paul is describing. A 90 degree center-slice twist in MC4D permutes 8 3C, 8 2C, and 4 1C pieces, but I think he is asking about a hypothetical twist that would only affect 4 3C, 4 2C, and no 1C pieces.

Please can someone illuminate - I am particularly interested in higher than four dimensions also i.e. could one always move a layer just affecting eight pieces in isolation (ignoring the piece that exposed no stickers)
