Congrats on finding this page! Here's a problem I made: \\
Suppose a positive integer with all digits non-zero is considered \textit{almost unique} if there are fewer than 
permutations of its digits. For example, 
is [i]almost unique[/i] since it has 
permutations,(, 
, and 
), while 
is not since it has 
permutations, (, 
, 
, 
, 
, 
). How many \textit{almost unique} numbers less than 
are there?
