The idea was that there ought to be three each of {black, length 1}, {black, length 2}, ..., {light grey, length 3}, which determines the distribution of lengths in the BR space and leaves only two options; I forget what halfassed justification I had for preferring one over the other.ghttp://www.mccaughan.org.uk/g/noreply@blogger.comtag:blogger.com,1999:blog-2800316528417070757.post-77445195670898770932012-11-07T02:35:26.590+00:002012-11-07T02:35:26.590+00:0026: lines from W, centre, E dots rotate clockwise,...26: lines from W, centre, E dots rotate clockwise, each step being 45 degrees if possible but 180 degrees at the edges.<br /><br />29: take shape from L column, replace its edges with what's in middle column, get R column. Note the orientation of the middle column to distinguish A from E.<br /><br />33: each NW-SE broken diagonal consists of two wavy lines and their union.<br /><br />34: what the fuckety fucking fuck?<br /><br />35: reflect arrows on left in mirrors in middle to get arrows on right.<br /><br />36: sorry, my brain exploded.<br /><br />37: we're working TL to BR in reading order. The progression of black squares is obvious. One filled circle begins at (1,1) and moves right one space each time, moving down to the start of the next line when it reaches the end. Another does the same starting at (3,1). An empty circle starts at (1,1) and does something I haven't quite worked out. The black squares are in front, then the empty circles, and the filled circles at the back. This is enough to determine the answer. (I *think*. One horrible possibility is that actually there are two empty circles and the "z-order" changes in some funny fashion, in which case one other answer might be just barely possible.)<br /><br />38: moving L->R and T->B, apply a stretching operation for a single-headed arrow and a colour interchange for a double-headed arrow.<br /><br />39: OMG. Perhaps there's something like ternary arithmetic going on here, but I wasn't able to figure it out in the time available. I'm not going to try now because it's well past bedtime.<br /><br />Hope this helps.ghttp://www.mccaughan.org.uk/g/noreply@blogger.comtag:blogger.com,1999:blog-2800316528417070757.post-71545856366872445532012-11-06T22:26:26.789+00:002012-11-06T22:26:26.789+00:00Ah, and 26 (in retrospect) is presumably G - the s...Ah, and 26 (in retrospect) is presumably G - the second set of lines have rotated, and are now outside the visible square.<br /><br />I think 29 is E, but I find that only weakly convincing.William M.
