 A240949 Number of partitions of n with the property that if two summands have the same parity, then their frequencies have the same parity. 1
 1, 1, 2, 3, 5, 6, 11, 11, 21, 20, 38, 31, 67, 51, 107, 83, 172, 126, 263, 192, 399, 299, 584, 437, 857, 648, 1218, 941, 1743, 1351, 2438, 1912, 3399, 2708, 4672, 3750, 6439, 5193, 8712, 7113, 11815, 9678, 15836, 13056, 21186, 17609, 28080, 23438, 37210, 31181, 48819, 41182, 64039, 54188, 83374, 70923, 108364, 92587 (list; graph; refs; listen; history; text; internal format)
 OFFSET 0,3 COMMENTS The parities of all even parts must be equal and the parities of all odd parts must be equal. LINKS Alois P. Heinz, Table of n, a(n) for n = 0..1000 EXAMPLE For example: for n=5 the partition 3,1,1 is not counted, because 3 and 1 have the same parity, but the frequency of 3 and the frequency of 1 have different parity.
