in thread Scrabble word arrangements with blank tiles
The more I think about it, the more I think I've got it completely wrong, but then, I think the OPs figure are also wrong
Looking at the simplest of the OPs figures, 2 tiles where one is blank, there must be at least 76 unique combinations ('A' | blank, 'A' + blank and blank + 'A' where bank can't equal 'A') so I can't see how the OP came up with their figures.
I haven't come up with a formula to match this premise as yet, but I'm sure my original formula is totally wrong. I would like some clarification from the OP before I try to figure out the correct formula.
