try:

use bigint;
print 2**(2**(2**1000)));

If you have a REALLY BIG computer, try:

print 2**(2**(2**(2**(2**(2**(2**10000)))));

Call that number JEB.

The solution to the problem "JEB has how many prime roots?" is
unfeasible in Sazonov's sense.

Of course, no number is "infinity".  Perhaps if Sazonov had counted
instead of particles, relations between particles and relations between
relations between particles and relations between relations between
relations between particles we would have reached a high enough number
to be a useful measuring stick for "infinity".
