 A325702 Number of integer partitions of n containing their multiset of multiplicities (as a submultiset). 7
 1, 1, 0, 0, 2, 1, 2, 1, 3, 3, 8, 7, 10, 13, 17, 19, 28, 35, 38, 51, 67, 81, 100, 128, 157, 195, 233, 285, 348, 427, 506, 613, 733, 873, 1063, 1263, 1503, 1802, 2131, 2537, 3005, 3565, 4171, 4922, 5820, 6775, 8001, 9333, 10860, 12739, 14840, 17206, 20029, 23248 (list; graph; refs; listen; history; text; internal format)
 OFFSET 0,5 COMMENTS The Heinz numbers of these partitions are given by A325755. LINKS EXAMPLE The partition x = (4,3,1,1,1) has multiplicities (3,1,1), which are a submultiset of x, so x is counted under a(10). The a(1) = 1 through a(11) = 7 partitions:   (1)  (22)   (221)  (2211)  (3211)  (4211)   (333)    (3322)    (7211)        (211)         (3111)          (32111)  (5211)   (3331)    (33221)                                      (41111)  (32211)  (6211)    (52211)                                                        (42211)   (53111)                                                        (43111)   (322211)                                                        (322111)  (332111)                                                        (421111)  (431111)                                                        (511111) MATHEMATICA submultQ[cap_, fat_]:=And@@Function[i, Count[fat, i]>=Count[cap, i]]/@Union[List@@cap] Table[Length[Select[IntegerPartitions[n], submultQ[Sort[Length/@Split[#]], #]&]], {n, 0, 30}] CROSSREFS Cf.
