%N A347207 The number of overpartitions of n whose Frobenius symbols have only positive parts in the top row.
%C A347207 a(n) is also the excess of the number of overpartitions of n with an even number of overlined parts larger than the number of non-overlined parts over the number of overpartitions of n with an odd number of overlined parts larger than the number of non-overlined parts.
