Is that a joke? Patenting the fact that log10(256) is 2.408..., which
is about 2.4, which is 24/10? I really hope we are Poe'd... BTW, NAK
the comment - s/36/26/ in there; check it yourself -
$ echo '2^(8*27)' | bc
105312291668557186697918027683670432318895095400549111254310977536
which is 66-digit, not 65 as the estimate would be.
