It's better to view them as hyperedges of hypergaphs.

You don't need any particular examples if you have the blueprint. Read pages 37 and 38.

Honestly, i don't think there's such a list. At most, people recognize two styles of ordered pair definition: the Wiener-style and the Kuratowski-Style. https://blog.plover.com/math/wiener-pairs.html
Alternatives to these styles may be found only hidden as exercises in set theory/order theory textbooks

this sends ({1}, 3) and ({3}, 1) to the same set
