Hello again SeqFans,
more from our "Silly Sequences' Storage".
Here is P:
P is a permutation of the Naturals (by definition) and
P self-describes its own prime runs' sizes of
-concatenating the first 2 terms produces a prime --> 2+3 = '23'
-concatenating the next 3 terms produces a prime --> 1+4+23 = '1423'
-concatenating the next 1 term produces a prime --> '5'
-concatenating the next 4 terms produces a prime --> 6+7+8+19 = '67819'
-concatenating the next 23 terms produces a prime --> but which one?
... I'm not sure that the term X (after 32), is computable...
As always, "in building this sequence, always use the smallest available
integer not leading to a contradiction"...
