 OFFSET 1,1 LINKS Table of n, a(n) for n=1..40. EXAMPLE 25 (25 = 5^2) are 27 (27 = 3^3) are consecutive perfect powers. Since both are odd, then 25 is in this sequence. 128 (128 = 2^7) and 144 (144 = 12^2) are consecutive perfect powers. Since both are even, then 128 is in this sequence. CROSSREFS Cf.
