Each of the numbers 1 to 9 appears four times in the 6x6 grid. If a number appears twice in any row or column, it is mentioned in the relevant clue.

Hi Josie,

What a mess... It seems I forgot the first sentence... "Each of the numbers 1 to 9 appears four times in the 6x6 grid" :> Bah...

Regarding your question, yes, i wanted both the changes to appear in the same grid.

172453
428395
561519
974286
845167
383629

But now I see it is wrong. 7, for instance, appears only three times.
