{137} ≠ 137
if we remove all numbers from 137 nothing remains.
It is a matter of taste whether the empty set is nothing.
{{}} ≠ {}
Nothing is not what is in {{}}.
The set of all FISONs with each omissible FISON omitted is {F}\{F} = {}
Indeed, because {F} is not an element of F, which is why I'm wonderingThe set of all FISONs with the set of omissible FISONs omitted isThere is no reason to consider {{F}} at all.
{F}\{{F}} = {F}
We omit all F(n) which amounts to remove F.No, it amounts to the elements of F, not those of {F}.
Like all natural numbers amount to ℕ (not {ℕ})Like all FISONs amount to F, not {F}.
Neumann would like to have a word with you.Wrong.{{}} ≠ {}Homework: Show the same for the set of FISONs.
