Hi,

Resolution with TDP, track and anti-track from 3r5c2:
P(3r5c2) = {3r5c2, 3r4c4, 4r4c6, 8r6c46, 7r6c2, ...}
P'(3r5c2) = P(8r5c2) = {8r5c2, 8r4c9, 8r6c46, 7r6c2, ...}
=> r6c2=7. stte.

Thanks! Personally I'm not a big fan of such backpedaling chains, so I hid it. It's a bit forced way to squeeze stte out of a natural btte. That's why I prefer Cenoman's, though I'd rather end it: ... - r2c2 = (732)r278c5. That said, now that I looked at my own chain again, I don't like the latter comma node (hard to read, and I think the comma is actually unnecessary). Seems there's a typo too (first node missing c5), but I'll just leave it there

Wow, nice. DIdn't find anything.

Thank you both !
As regards the end of my chain, I hesitated, and eventually, I couldn't depart from my propensity to cross the T's and dot the I's
