 OFFSET 1,2 COMMENTS These are the Heinz numbers of the integer partitions counted by A241638. A prime index of n is a number m such that prime(m) divides n. The multiset of prime indices of n is row n of A112798. LINKS EXAMPLE The sequence of terms together with their prime indices begins:     1: {}     6: {1,2}    12: {1,1,2}    14: {1,4}    15: {2,3}    18: {1,2,2}    24: {1,1,1,2}    26: {1,6}    28: {1,1,4}    33: {2,5}    35: {3,4}    36: {1,1,2,2}    38: {1,8}    45: {2,2,3}    48: {1,1,1,1,2}    51: {2,7}    52: {1,1,6}    54: {1,2,2,2}    56: {1,1,1,4}    58: {1,10} MATHEMATICA Select[Range[100], 0==Total[(-1)^PrimePi/@First/@If[#==1, {}, FactorInteger[#]]]&] CROSSREFS A324967(n) = A324966(n).
