EXAMPLE
Let hep(n) = n*(5n-3)/2. Then
a(1) = 7 = hep(2).
a(2) = 6426 = hep(51) = hep(4) * hep(9).
a(3) = 35224 = hep(119) = hep(2) * hep(4) * hep(8).
a(4) = 2077992 = hep(912) = hep(2)^2 * hep(3) * hep(31).
a(5) = 3610893055 = hep(38005) = hep(2)^3 * hep(5) * hep(277).
a(6) = 14209771072 = hep(75392) = hep(2)^4 * hep(31) * hep(32).
