Maybe I'm missing something here, but I think there are three sets of multiple solutions.

1) Lower left 9x9 sudoku.
In the left most two columns, switch the 4's and 6's that are next to each other.

2. Upper left 9x9 sudoku.
In the third and fourth columns, switch the 5's, and 9's.

3. Upper right 9x9 sudoku.
This one's more complex.
Make the middle three rows

2 9 A B 4 3 7 C 1
1 D E F 2 7 9 G 3
7 H 3 1 9 6 2 I 8

Then treating (A,B,C,D,E,F,G,H) as an ordered octuples, you have the solution:
(6,8,5,4,8,5,6,5,4)
I think
(8,5,6,5,6,7,4,4,5) and
(8,5,6,4,6,8,5,5,4) are also solutions.

2)	I misstyped in my last post. My first alternate solutions should read (8,5,6,5,6,8,4,4,5) not (8,5,6,5,6,7,4,4,5). Comment by: Josh. Made on the 06th Jan 2006.

3)	Hi Josh You are correct on the first two errors, many thanks for pointing them out. I am looking into the third error now. I knew that this puzzle would cause problems. melvyn Comment by: melvyn lawes. Made on the 06th Jan 2006.

4)	This puzzle has now been fixed. Thanks for your help. Comment by: Daniel (Site owner). Made on the 16th Jan 2006.

5)	As it stands, I think that the upper right square has at least two solutions for rows 4-5-6, i.e. 2-9-6-8-4-3-7-5-1 1-4-8-5-2-7-9-6-3 7-5-3-1-9-6-2-4-8 (as in the solution) and 2-9-8-5-4-3-7-6-1 1-5-6-8-2-7-9-4-3 7-4-3-1-9-6-2-5-8 Comment by: giovanni. Made on the 16th Apr 2006.

6)	In addition to the 2 solutions given by Giovanni, there is a third for the same three rows: 2-9-8-5-4-3-7-6-1 1-4-6-8-2-7-9-5-3 7-5-3-1-9-6-2-4-8 Comment by: Laurent. Made on the 22nd Apr 2006.
