Hello SeqFan,
is this of interest?
2,4,6,7,8,9,10,12,13,14,15,16,18,20,21,23,24,25,26,27,28,30,32,37...
P ^ ^ P ^ ^ ^ ^ P. ^ ^ ^ ^ ^ ^ P. ^ ^ ^ ^ ^ ^ ^ P.
2 4 6 7 ...
Self-describing sequence : A(n) indicates the quantity
of composite numbers which are between two successive
primes.
(this is not an accurate definition -- please help me to
rephrase!)
If this is of interest, could someone compute more terms?
best,
É.
