(wysinwyg web mail editor is perverse and impossible, starting fresh)

It might be possible to guess the formula for T(n,k) in http://oeis.org/A200785
from the formula for column 2 in http://oeis.org/A076264

a(n)=sum{k=0..floor(n/3), binomial(n-2k, k)(-1)^k*3^(n-3k)}

with the right generalization.
