COMMENTS

Numbers such that at least one run of 1-bits in their binary expansion has length >= A000040(1 + the total number of 0-bits anywhere right of that run).

EXAMPLE

3 ("11" in binary, A007088) is present as the length of that only run of 1's is 2, and 2 >= prime(1+0), where 0 is the total number of 0's to the right of that run.

60 ("111100" in binary) is NOT present as 4 < 5 = prime(2+1).
