I'd be interested if anyone would verify that all the numbers above are unsolvable for the '''24''' game. -- [[User:Gerard Schildberger|Gerard Schildberger]] ([[User talk:Gerard Schildberger|talk]]) 23:31, 3 January 2019 (UTC)
:'''Edited:''' I accidentally listed the groups with only one solution as unsolvable. Fixed now.
Um. You may want to re-read the task rules, specifically the one stating "The order of the digits when given does not have to be preserved."▼

That being the case, there are only 495 unique combinations of 4 non-zero digits. This is ALL of them.▼

:But even putting that aside, with a quick peek at your "unsolvable" list, I pick out 1164 (1*1*6*4), 1183 (1*1*8*3), 2232 (2*2*3*2) and many other that don't require digit reordering. I think you need to revisit your filtering algorithm. --[[User:Thundergnat|Thundergnat]] ([[User talk:Thundergnat|talk]]) 02:22, 4 January 2019 (UTC)
