A cyclic sequence. The period is 6767.

If an array is made of columns of -nacci sequences, fibo-, tribo- etc. all starting w. 1,1,2 etc, the nw to se diagonals can be extended by computation. The above minus the first digit is diagonal 4. See A159741 for details. [From Al Hakanson (hawkuu(AT)gmail.com), Apr 20 2009]
