I don't know a better way of showing the symbolics than with screen shots.

For N=40000 all columns show NaN. The 38G gives correct values for 40000 (& in fact for 1000000).

Yes, & the values for 32767 are all correct. Obviously the problem seems to exist for all sequences if the index N gets higher than 32767 (= 2^15-1). Also for simple sequences like U1(N)=N or even U1(N)=1. So, most likely a limitation issue for the index variable.
