What is an unlimited board for an ultrafinitist. (Ok, that was perhaps

Those are not universes, but computational histories. Assuming comp  
there is a first person indeterminacy, which makes "physical  
appearances" or "physical universe" emerging from the infinity of such  
computational and universal computation. I suggest you read the UDA  
papers. I guess you were not yet on the list when I explained why  
"Wolfram" sort of computational physics, based on cellular automata,  
does not work.
And quantum mechanics confirms this by giving indirect but strong  
evidences on the existence of many statistically interfering  

The question about the existence of a mathematical structure  
describing the physical appearance is open, but we know already it is  
not a structure such that it makes sense to say "I belong to it", even  
if it makes sense to say "he" belongs to it. But "he", from his first  
person point of view belongs to an infinity of such history (or comp  
is false, which is the case normally for an ultrafinitist).
