%N Number of partitions of n such that (greatest part) = (multiplicity of least part).

%F A240178(n) + a(n) + A240184(n) = A000041(n) for n >= 0.

%e a(8) counts these 3 partitions: 41111, 32111, 22211.

%t z = 60; f[n_] := f[n] = IntegerPartitions[n];

%t t1 = Table[Count[f[n], p_ /; Max[p] < Count[p, Min[p]]], {n, 0, z}] (* A240178 except for n=0 *)

%t t2 = Table[Count[f[n], p_ /; Max[p] <= Count[p, Min[p]]], {n, 0, z}] (* A240182 *)

%t t3 = Table[Count[f[n], p_ /; Max[p] == Count[p, Min[p]]], {n, 0, z}] (* A240183 *)
