In the attached table, convert the 403 by 2 elements to a matrix of 13 by 31 or to 31 by 13 elements.
Every 13 rows contain the same variables. Each of these 13 rows could be called a PRN. Hence, there are 31 PRNs with 13 variables each.

Oh, I made a small mistake!
I have just added 'stable' option to the unique function to keep the variable name order in my previous answer. Thank you for pointing it out.
