%N A347206 The number of overpartitions of n whose Frobenius symbols have only odd parts in the top row.
%C A347206 a(n) is also the excess of the number of overpartitions of n with an even number of non-overlined parts larger than the number of overlined parts over the number of overpartitions of n with an odd number of non-overlined parts larger than the number of overlined parts.
