> powers of all possible combinations; power is defined as the square of the largest number in a sequence

My problem with this challenge definition is that a sequence is an ordered set, much like Perl arrays.

But it seems to me the solutions presented are based on unordered subsets.

For clarification:

[2,3,4,5] may be a subset of [0 ..10] and there is only one subset of length 4 possible with 2 minimal and 5 maximal.

But 2 sequences for length 4 °

Am I mistaken and is this a case of TL;DR?

Thanks for clarification.

PS: Mohammed's example doesn't help because you need longer arrays to see the difference.

Update

°) And generally n! for length n+2
