%N Product between n-th prime and next perfect square.

%H Vincenzo Librandi, <a href="/A229497/b229497.txt">Table of n, a(n) for n = 1..1000</a>

%F a(n) = A000040(n) * A145445(n).

%e 63 is in the sequence because 7*9=63.

%t (Floor[Sqrt[#]] + 1)^2 # &/@Prime[Range[80]]

%Y Cf. A000040, A145445, A106044.
