What is the last term of the zeroless seq S?
The length of the successive integers
is given by the successive digits of S
Slenghts = 1,2,1,2,2,2,2,3,2,4,2,5,1,1,1,...
S was always extended with the smallest
integer not occuring earlier and not
leading to a contradiction.
Note that S will show only nine 1's
as there are only nine 1-digit integers
in Z (all zeroes are forbidden in S as
a zero would produce an integer of
length zero later -- which has no sense).
(we could have decided that zero produces
a 10-digit integer later in the seq. --
but we didn't select this option here).
The seq. P obeys the same rules -- but
all terms of P must be primes: what
is the last term of P?
