%N Number of partitions p = [x(1), ..., x(k)], where x(1) >= x(2) >= ... >= x(k), of n such that max(x(i) - x(i-1)) < number of parts of p.
%C For the partition [n] of n, "max(x(i) - x(i-1))" is (as in the Mathematica program) interpreted as 0.
%F a(n) = A241826(n) - A241825(n).
%F a(n) + A241823(n) + A241825(n) = A000041(n) for n >= 0.
%e a(6) counts these 8 partitions: 6, 33, 321, 3111, 222, 2211, 21111, 111111.
