HP Prime: Connel Sequence - Gerald H - 03-10-2015 03:33 PM
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. [attachment=1769][attachment=1770][attachment=1771] RE: HP Prime: Connel Sequence - Gerald H - 03-10-2015 03:59 PM
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). RE: HP Prime: Connel Sequence - Didier Lachieze - 03-10-2015 04:40 PM

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. RE: HP Prime: Connel Sequence - Gerald H - 03-23-2015 07:42 AM
