COMMENTS

a(n) = m * (A046083(k)*A046084(k)*A009000(k))^2 for appropriate, not necessarily unique m and k.

Index entries for linear recurrences with constant coefficients, signature (2, -1).

FORMULA

a(n) = n*60^2.

EXAMPLE

5^2+12^2=13^2: 5^2, 12^2 and 13^2 are divisors of

608400=(13*5*3*2^2)^2, therefore 608400 is a term.
