 1, 1, 1, 2, 3, 4, 6, 8, 11, 15, 21, 28, 39, 51, 68, 88, 116, 149, 193, 245, 314, 396, 501, 628, 788, 979, 1218, 1505, 1859, 2283, 2802, 3421, 4175, 5072, 6155, 7442, 8989, 10819, 13008, 15593, 18669, 22292, 26587, 31631, 37588, 44567, 52779, 62377 (list; graph; refs; listen; history; text; internal format)
 OFFSET 0,4 COMMENTS Partitions of n into at most ceiling(n/2) parts and with at least 1 part greater than or equal to n - floor(n/2). LINKS FORMULA a(n) = A000041(n)/2 if A000041(n) is even and (A000041(n)+1)/2 if A000041(n) is odd. EXAMPLE a(5) = 4 because the 4 nonisomorphic partitions of 5 are (5), (4,1), (3,2), (3,1,1).
