Example

A300566(1) = 8748 is the smallest z such that z^6 = x^4 + y^5 for some x,y > 1, and the smallest such y is a(1) = 52488. It then follows that x = (8748^6 - 52488^5)^(1/4) = 472392.
A300566(2) = 10368 is the second smallest z such that z^6 = x^4 + y^5 for some x, y > 1, and the smallest corresponding y is a(2) = 62208. It then follows that x = (10368^6 - 62208^5)^(1/4) = 746496.
