Hi Cenoman,

Your last two links aren't alternating. How about a bit different route:

... - (1=284)r567c6 - r7c3 = (497)r2c319 - (7=8)r3c8 => -8 r3c7,r6c8

Hi Steve,

SteveG48 wrote:(1=247)b8p137 - 7r3c4 = 4r3c4&(794)r2c159 - 4r9c14 = (491)b8p369 => -1 r7c23,r8c6 ; stte

A slight problem with your last node, but easy to fix:

... = (421)b8p379 => -1 r7c23,r8c6

or:

... = (49-1)b8p69 = 1r7c46 => -1 r7c23,r8c6

Your original approach could be made to work as well:

... = (49,1)b8p9631 => -1 r7c23,r8c6

Thanks, SpAce. Actually, that's how I first wrote it. Don't know why I changed. :?
