Of course you could just follow the reference given in the OEIS:

It's quite a worthwhile and enjoyable read.

The answer is that the 89th(!) number is not an integer.

EDIT: You'll also find that the same problem for fourth powers yields a non-integer for the 97 number, for fifth powers at the 214th position ...
