For corresponding x values see A134107.
EXAMPLE
a(1)^2 = 3^2 = 9 = A134107(1)^3 - 207 = 216 - 207.
a(2)^2 = 39^2 = 1521 = A134107(2)^3 - 207 = 1728 - 207.
a(3)^2 = 75^2 = 5625 = A134107(3)^3 - 207 = 5832 - 207.
a(4)^2 = 172^2 = 29584 = A134107(4)^3 - 207 = 29791 - 207.
a(5)^2 = 5511^2 = 30371121 = A134107(5)^3 - 207 = 30371328 - 207.
a(6)^2 = 6022^2 = 36264484 = A134107(6)^3 - 207 = 36264691 - 207.
a(7)^2 = 223063347^2 = 49757256774842409 = A134107(7)^3 - 207 = 49757256774842616 - 207.
