No, Wilbert is correct.
There is no [-4,-3] segment. For Spline 64, we have eight points, hence
seven intervals/polynomials.

Also I think this constraint is also available 12*b3 + 2*b2 = 0, not sure about the 12 maybe it should be 9, my brain is quite rusty on this stuff.

Can you say where this constraint comes from?

Also we know a0=1 and b0,c0,d0=0 so we may be able to reduce the equation clutter even more, making it feasible to deduce spline100, spline144, spline196 and spline256 coefficients

If you use a tool like Maple, does the equation clutter matter?
Unless the tool has a limit on the size of equations it can solve, isn't it just a matter of following Wilbert's method with the appropriate number of polynomials?
