Composites for which the row of the prime-composite array (A063173) includes the leftmost element of a zero-only antidiagonal.

9, 15, 21, 35, 45, 51, 65, 69, 95, 99, 119, 129, 135, 141, 155, 161, 189, 209, 215, 219, 249, 261, 299, 303, 305, 309, 321, 339, 341, 363, 365, 371, 399, 405, 413, 425, 441, 453, 465, 545, 555, 615, 623, 639, 651, 705, 713, 725, 729, 741, 771, 783, 803, 819

1,1

Neil Fernandez, <a href="http://www.borve.demon.co.uk/primeness/pcarray.html">The prime-composite array, B(m,n), and the Borve conjectures</a>

The 8th composite is 15. In the prime-composite array (A063173), all of the elements in the antidiagonal containing T(8,1) are 0. So 15 is in the sequence.

Cf. A063173, A063175, A063176.
