Yes! There was no need of going around. Sometimes I can't see the obvious. Thanks again.SpAce wrote:Ngisa wrote:(4=7)r7c4 - r7c9 = r9c9 - (7=2)r9c56 - (2=4)r34c6 => - 4r4c4; stte
Hi Clement! A very nice chain, especially if you drop the redundant nodes (colored red). You could then also write it as a very short ALS XZ:
(4=792)b8p189 - (21=4)r34c6 => -4 r4c4, r8c6; stte

However the box externals lead to the same elimination -4r8c6.
