Kraken cell (178)r9c6
(1)r9c6 - (1=93)r9c17 - r4c1 = (3)r4c3@
(7)r9c6 - r1c6 = r1c7 - r4c7 = (7)r4c3@
(8)r9c6 - r4c6 = (8-2)r4c5 = (2)r4c3@

The solution for totuan, Cenoman, and the program is the same, using the same 8 Truhs.
Image
Cell Type Blossom Loop: 178r9c6 => r9c38 <> 1, r28c1 <> 3, r4c35 <> 4, r4c35 <> 6, r2c6,r6c7 <> 7, r28c6 <> 8, r9c348 <> 9
Burring Loop: 1r9c6 - (1=93)r9c17 - r4c1 = (3-2)r4c3 = (2-8)r4c5 = r4c6 - 8r9c6
Burr Branch 1: 7r9c6 - r1c6 = r1c7 - r4c7 = 7r4c3

Program Algorithm:
Find a burring loop. Find a branch for each burr, with its endpoint in a weak region of the loop or other branches. If the burr happens to be in a weak region of the loop or other branches, there is no need to find a branch for it anymore. All truths in the structure do not overlap.
