Hi,
This is a repost with different criteria.

42 blocks of data each containing 6 cells.
Each cell can be either empty or populated.

How many combinations given that, for example :
Block 1 with 1 cell poulated, all others empty, is the same as Block 2 with
1 cell populated, all others empty etc.

The answer may be the same as in the previous post - my math / stats is not
up to it !!

regards,
Don
