For example n=194 results in [[0, 5, 13], [1, 7, 12], [3, 4, 13], [3, 8, 11], [5, 5, 12], [7, 8, 9]] or six triads, the number 194 is the smallest for 6 triads. His program works very well, and I verified it for the values of 1 <= n <= 1e7.

I am happy to send you the 41374 row file of currently determined values, for testing purposes. Maybe also ask on the seqfan mailing list. > "the number 194 is the smallest for 6 triads" I presume there are related sequences in the OEIS. -- Ruud
