62 wrong views in Digha Nikaya 1.
For example: the cosmos is eternal, or not eternal, or finite, or infinite; the soul and the body are the same thing, or they are different things; after death, a Realized One exists, or doesn’t exist, or both exists and doesn’t exist, or neither exists nor doesn’t exist.

Majjhima Nikaya 2 (a question about those, 5 to 14, is that partially not reflecting about samsara? Or do I understand that wrong?)
And the Sutta where someone asked the buddha if all the world is becoming enlightened or half or a third? I csnnot find this sutta in google.
These are all I know of, are there more?
Thanks for every contribution.
