COMMENTS

a(n) is in this sequence iff n (base 3) = A007089(n) has a block (not a subblock) of a prime number (A000040) of consecutive zeros.

FORMULA

a(n) is in this sequence iff n (base 3) = A007089(n) has a block (not a subblock) of a prime number (A000040) of consecutive zeros.

FORMULA

a(n) is in this sequence iff n (base 3) = A007089(n) has a block (not a sub-blocksubblock) of a prime number (A000040) of consecutive zeros.

EXAMPLE

81 is not in this sequence because 81 (base 3) = 10000 has a block of 4 consecutive zeros and it does not matter that this has sub-blocks subblocks with 2 or 3 consecutive zeros because sub-blocks subblocks do not count here.
