COMMENT
|
The nonnegative integers A001477 = A141468 U A000040 are reshuffled.
The positions 0,1,2,3,.. in this sequence here are marked as prime or non-prime, and the nonnegative integers
are filled in at positions of their opposite class.

|
EXAMPLE
|
The positions 0,1,2,3,4,5,... are N,N,P,P,N,P... (N=non-prime, P=prime),
and are filled by two prime, then two non-prime, one prime, one non-prime member of A001477.
