64^64 is

39402006196394479212279040100143613805079739270465446667948293404245721771497210611414266254884915640806627990306816

to be precise.

End of 1997, there was a similar discussion going on. Maybe a quick look into
the archive might help. Someone posted a link to a web-page that tries to answer
exactly this question. However, the number I had in mind is significantly bigger
than 64^64.

I do not think it is relevant to assume that a computer will handle all those
moves. It is an academic question that deserve an answer and it somehow eludes
me what the number of atoms in our known Universe has to do with this.

Especially, since we do not know how much degrees of freedom are in a small drop
of water. Yes, we have baryons and leptons of a finite number in this drop. But
also the field particles add to the degree of freedoms. Unfortunately, QCD does
not describe nature to the fullest extend. So, even 64^64 might be too small to
perfectly describe a drop of water.
