COMMENTS

The entries up to 66 have been checked, but the remaining entries are based on my hypothetical formula (see A101513). (It would be easy to check them.)

I have checked that these are correct entries from the triangle, but not that they match the hypothetical formula (from A101513). - Joshua Zucker, May 20 2006
