If you're looking for the "code" column, they're all 0700.  See the man 
page for gdisk.  The section describing the "l" command clarifies:

               For ease
               of data entry, gdisk compresses these into two-byte 
               hexadecimal) values that are related to  their 
equivalent  MBR

               ... Note that these two-byte codes are unique to gdisk.

The codes printed by gdisk don't actually appear in the GPT.
