:: I don't need to re-read the task rules, I programmed the REXX program which does NOT preserve the order of digits when presenting solutions, but it does honor the original number being processed and shows (all) the solutions for that number, for any order of its digits. The task's requirement said that it ''does not not have to be preserved'', it didn't say ''should not be preserved''. I choose to preserve the order of digits for the REXX entry. -- [[User:Gerard Schildberger|Gerard Schildberger]] ([[User talk:Gerard Schildberger|talk]]) 00:27, 5 January 2019 (UTC)
:::Who said anything about REXX? Or even the actual task code? My point was: if say, 1678 is unsolvable, then so is 1687, 1768, 1786, 1867, 1876, 6178, 6187, 6718, 6781, 6817, 6871, 7168, 7186, 7618, 7681, 7816, 7861, 8167, 8176, 8617, 8671, 8716 & 8761, and there isn't any point in listing all of them '''unless the solver is only checking numbers with preserved order'''. Like I said, there is only a total of 495 unique combinations of 4 non-zero digits. Of those, 91 are unsolvable for 24. Even if you count all possible permutations of each combination, there are only 757 unsolvable "numbers". Not sure where you are getting the 1263 from. --[[User:Thundergnat|Thundergnat]] ([[User talk:Thundergnat|talk]]) 14:11, 5 January 2019 (UTC)
:That being the case, there are only 495 unique combinations of 4 non-zero digits. This is ALL of them.

: Yeah, except that isn't the list Gerard posted, that was mine. Gerards list (which he has since deleted) had 2501 "unsolvable" numbers in it where '''at least''' 1744 of them were, in fact, solvable. --[[User:Thundergnat|Thundergnat]] ([[User talk:Thundergnat|talk]]) 14:11, 5 January 2019 (UTC)
