Any ideas? I sincerely appreciate your help.

Some logic
-> product (sort by top 3 - based on how many rows it appears on)
----> skew (sort by top 5 skews from the products found above)
----> count of skews

I hope that helps explain a bit more.
A bit more, yes. But still not clear. In your sample input there are 6 occurrences each of products p1, p2, p3, and p4. You say you want the top 3 products, but your sample output only shows 2. (And since there are four products with the same number of occurrences, you don't say how to choose which 3 of those 4 should be chosen.) Your sample output didn't show the top 2 product/skew pairs p1/12345 and p2/23456 both of which appear 6 times even though p1 and p2 appear the same number of times as p3 and p4???

From what you did with your 1 count sample, you chose the last two of the set of the four most common products based on the fact that their product names sorted last. Is that really what you want?

If there are ties, should your results include all products that match the number of occurrences of the third most common product? If there are ties in the number of appearances of a skew within a product, should the results include all skews with the fifth most common skew within that product?

Will a single skew ever appear with more than one product, or are skews supposed to be unique to a product.

setup.types

setup.types(5)						      Easy Software Products						    setup.types(5)

NAME

       setup.types - epm gui setup types file format.

DESCRIPTION

       The EPM setup program normally presents the user with a list of software products to install, which is called a "custom" software installa-
       tion.

       If a file called setup.types is present in the package directory, the user will instead be presented with a  list  of  installation  types.
       Each  type has an associated product list which determines the products that are installed by default. If a type has no products associated
       with it, then it is treated as a custom installation and the user is presented with a list of packages to choose from.

FILE FORMAT

       The setup.types file is an ASCII text file consisting of type and product lines. Comments can be inserted by starting a line with the pound
       sign  (#).  Each  installation type is defined by a line starting with the word TYPE. Products are defined by a line starting with the word
       INSTALL:

     TYPE Typical End-User Configuration
     INSTALL foo
     INSTALL foo-help
     TYPE Typical Developer Configuration
     INSTALL foo
     INSTALL foo-help
     INSTALL foo-devel
     INSTALL foo-examples
     TYPE Custom Configuration

       In the example above, three installation types are defined. Since the last type includes no products, the user will be presented  with  the
       full list of products to choose from.
