By discrete set, I mean sorting a given number of items into different orders, so that no two sets are alike.
Example, 4 items: 1234 3142 2413 4321
It seems related to a "derangement", but is more specific. So maybe there's a specific term for this, besides "discrete set", which is all I could think of.
Now that I'm looking at latin squares, the following example of a latin square actually repeats sequences between columns (such as 34, 21, 43), whereas my example above does not.
1234 2143 3412 4321
Is my non repeating example a particular kind of latin square or is that not distinguished from other latin squares which repeat sequences?
