I would like the output to be (effectively removing the last item as in the example) {{0.1, 0.2, 5}, {0.1, 0.3, 7}, {0.2, 0.2, 1}} DeleteDuplicates[data] doesn't work for me as it uses all A, B and C in the duplicate detection and removal.

And I ended up with 3360 unique strings: import itertools unique = {} for p in itertools.permutations (list ("aaamottu"), 8): unique [p] = True len (unique) I'd like to know how to get that number using plain old math. P r n ( 8, 8) gives 40320.

6 hours ago From what I've read (I'm no mathematician), a set can have identical elements within it when it is defined, but when working with sets or comparing sets, the duplicates are ignored. So {1, 1, 2} is the same as {1, 2} is the same as {2, 1}. A multiset is where multiple instances of an element matters. $\endgroup$ –

8 hours ago The original list is : [1, 3, 5, 6, 3, 5, 6, 1] The list after removing duplicates : [1, 3, 5, 6] Method 3 : Using set() This is the most popular way by which the duplicated are removed from the list. But the main and notable drawback of this approach is that the ordering of the element is lost in this particular method.

1 hours ago Increasing $r$ increases the chance of duplicates eventually leading to a uniform distribution. Decreasing $r$, on the other hand, decreases the chance of duplicates eventually leading to a distribution of singleton sets. For the latter, it turns out there is another implementation that seems to perform unreasonably well for sparse vectors.
