 OFFSET 0,1 LINKS FORMULA a(n) = 2*A130202(n). Multiplication by 2 preserves odiousness, hence this sequence is twice odious triangular numbers. MATHEMATICA Select[Table[n(n + 1), {n, 100}], OddQ[Plus @@ IntegerDigits[ #, 2]] &] CROSSREFS Cf. This sequence is the intersection of odious (A000069) and oblong (A002378) numbers. Sequence in context: A278847 A193270 A076391 * A076392 A048373 A066563 Adjacent sequences:  A130198 A130199 A130200 * A130202 A130203 A130204 KEYWORD nonn AUTHOR Tanya Khovanova, May 16 2007 STATUS approved
