HP Prime: Connel Sequence
Connel sequence or
http://oeis.org/A001614 Here the symbolics of a sequence app to show Column 1: Connel sequence Column 2: Partial sums of column 1 Column 3: Numbers missing from the Connel sequence Column 4: Partial sums of column 3. I don't know a better way of showing the symbolics than with screen shots.

RE: HP Prime: Connel Sequence
Now the complaint:
For N=32000 all columns are correct. For N=40000 all columns show NaN. The 38G gives correct values for 40000 (& in fact for 1000000).

Obviously the problem seems to exist for all sequences if the index N gets higher than 32767 (= 2^151). Also for simple sequences like U1(N)=N or even U1(N)=1. So, most likely a limitation issue for the index variable.
