How big is infinity?

Hi Deis,
Thaks fo makig this fatastic video!
A few yeas ago I made a sculptue etitled ‘The Hads of Cato’, that used the Cotiuum Hypothesis as a jumpig off poit. Afte I fist ead about Geog Cato ad set theoy, I had a deam that he had a ifiite umbe of figes o each had. I became obsessed with ceatig a sculptue out of that deam. Hee is a lik to a shot book I made about the poject. You might be oe of the few people that would actually get a kick out of it! https://www.imesta.com/woks/286/

Hi Dennis, Thanks so much for this very interesting video. At 1:15 you mention that matching is a more fundamental operation than addition. Are there any other operations that are like matching in that respect? Are there operations more fundamental than matching?
