Wolfram Alpha can compute the possible relationships given any sequence of relationships, not just the ones that people might use in real life. For instance, consider “my cousin’s cousin’s niece’s grandfather”:
The first pod shows the family tree based on what we just entered. It assumes that none of the people we mentioned are the same. Only the first few on the family tree are related in a traditional sense.
The next pod shows possible simplifications. I would never have figured this out myself, but if my cousin’s cousin was myself and the grandfather referred to was on the same side of my niece’s family as myself then her grandfather would be my sibling’s father, which would be my father. We get the other possible relationships, and also the neat statistic on the number of relationships that don’t have a traditional label like “father” such as the one pictured in the first pod.
Sometimes it’s best to let another do the relationship thinking. That’s thinking best left to Wolfram|Alpha.

Persze az igazi majd akkor lesz, ha a bérmakeresztanya ángyának a térdekalácsát is el tudja helyezni
