I have put a picture of the worksheet on my profile if any kind soul would have a look as we cannot agree on what this sheet means.
Does it mean you can only have combinations of 0 thimbles, 1 thimble, 2 thimbles on each set of shelves i.e. 012, 021, 120, 210, 102, 201 - 6 solutions
Or does it mean you can have 0thimbles, 1 thimble or 2 thimbles anywhere on the shelves i.e. 000, 001, 002, 222, 210, 101, 111 etc
We have been visiting family this evening and it seems to be split as to which way to do it.
Thanks in advance
