Year-end appeal: Please make a donation to the OEIS Foundation to support ongoing development and maintenance of the OEIS. We are now in our 56th year, we are closing in on 350,000 sequences, and we’ve crossed 9,700 citations (which often say “discovered thanks to the OEIS”).

 A279953 Numbers that cannot be partitioned into two or more distinct even-valued terms or distinct odd-valued terms of the sequence. 1

%N Numbers that cannot be partitioned into two or more distinct even-valued terms or distinct odd-valued terms of the sequence.

%C There are interesting large jumps within the sequence (e.g., more than doubling from 487 to 1457).

%C There appears to be the same number of even terms aa odd terms in the sequence.

%H Alois P. Heinz, <a href="/A279953/b279953.txt">Table of n, a(n) for n = 1..97</a>

%e 10 is not in the list, as it is 7+3, both odd terms.

%e 66 is not in the list, as it is 50+14+2, all even terms.

%e 38 is in the list since it cannot be represented as the sum of all even terms or all odd terms.

%K nonn

%O 1,2
