Should we change A186750 to start off 0, -3, 6 instead of 3, 6? This
would be to bring it in line with A072191, a(n) = a(n-1)^2 + 2, redefining
A186750 as a(n) = a(n-1)^2 - 3.
Pro: Adding the initial 0 allows this sequence to come up in searches that
currently result in no matches. The Mathematica can be simplified to
- 3 &, 0, 9].
Con: It would make this a keyword:sign sequence just for one term. The
sequence starting 3, 6 is part of an array.
