→The Pedigree list
A text list is more actionable when sharing with family and other genealogists than a diagram. A diagram makes understanding the relationship easier. But a list can be transcribed into a form or another program more easily.
An example of Piatt's pedigree is shown in Figure 3. You will notice that the the lines for ancestors 152 and 153 are marked as being the same as ancestors 68 and 69 (Edward Christiansen and Elizabeth Thomas). This is where there is pedigree collapse for Piatt. The rest of the list will crop out the ancestors of 152 and 153 because they too are duplicated.
But which children were the siblings? Just divide the ancestor number by 2 to get the number of their child. Half of 152 is 76 (Nathanial Christiansen) and half of 68 is 34 (off-screen in Figure 3 but this is Joseph Christiansen). You can use this method in any Ahnentafel Numbering System. You can also use [https://wikipedia.org/wiki/Ahnentafel#Deductive_reckoning "deductive reckoning"] determine their exact relationship to the #1 person by their number.
