You tried:
> f: Integer -> Integer;
> f(0)==1; f(1)==2;
> f(n)==sum(f(i)*f(n-i), i=0..(n-1))
Try
f: Integer -> Integer;
f(0)==1; f(1)==2;
f(n)==reduce(+,[f(i)*f(n-i) for i in 1..(n-1)])
I have no good explanation why sum won't work. (Well, I know why it happens
internally. I'm looking for a solution...)
