I want to create a code that will analyze an array, and list the number of times a sequence appears regardless of the order?
A=[1, 2, 3; 3, 2, 1; 2, 3, 2; 2, 1, 3];
For example, in the above array I want to know how many times equal sequences appear and the numbers in that sequence. So in this case the code would recognize that "1, 2, 3", and "3, 2, 1" and "2,1,3" are the same regardless of order, list the number sequence and how many times it appears. So, "1,2,3" and appears 3 times. I tried my best to word this without sounding confusing. I'll answer any questions regarding what i'm trying to achieve I'm just not sure how to code something like this.

Will the sequence to be found always occupy the whole row?
Is it necessary to figure out what the sequences are and how long they are?
