Double Tridagon (123)@b1245 (*,^) having three guardians each (5r4c5, 4r5c6, 6r6c4: *) and (6r4c6, 5r5c4, 4r6c5: ^)
1. Tridagon 1 (*)
(5)r4c5 - r5c4 = (58)r79c4
(6)r6c4
(4)r5c6 - r6c5 = (4589)r79c45
=> -6 r79c4 (+6 r6c4)

2. Tridagon 2 (^)
(5)r5c4 - r4c5 = (59)r79c5
(4)r6c5
(6)r4c6 - r6c4 = (6589)r79c45
=> -4 r79c5 (+4 r6c5); lclste
