There was no need to post a new question, as this ask exactly the same as the old one!

comment Finding all the zeroes in $100!$
The sequence $2, 30, 472, 5803, 68620, 782336, \dots$ is the number of zero digits in $10^k!$ starting from $k=1$. This is not in the OEIS (yet?). The next one, $10^7!$, has something like $1.5\times 10^8$ digits, and probably one needs to do something smarter than my trivial code above to compute the number of zeroes.

comment What's the relation between a fixed point and a root of a function?
The fixed points of a function $f$ are the same as the zeroes of the function $g(x)=f(x)-x$, and conversely, but these are two different functions.

None, really. ${}$

comment zero object in the category of group schemes
Groups schemes are no the same as schemes: they have an "identity element". Try to find the zero object in the category of groups, first.

comment Literature request: Method for constructing projective manifolds
I guess that you are after toric varieties. You should most certainly look at Cox's book on the subject.

comment Is trace of regular representation in Lie group a delta function?
I will close this one. I suggest you edit the old one if you want to change it.

comment Is trace of regular representation in Lie group a delta function?
The simple answer is that there is no trace. You are trying to compute something that simply does not make sense.

Your question on MO was moved here already (you can find it at math.stackexchange.com/questions/1232328/…)
