Definitions are different:
A061433 a(n) = largest n-digit square
A069659 a(1) = 1; then the largest n-digit perfect
power
while all entries are the same(?):
9, 81, 961, 9801, 99856, 998001, 9998244, 99980001,
999950884, 9999800001, 99999515529, 999998000001,
9999995824729, 99999980000001, 999999961946176,
9999999800000001, 99999999989350756,
999999998000000001.
Shouldn't the valuable comment in A069659:
"Are there terms which are not perfect squares?"
be included (with rewording) into A061433,
and A069659 deleted?
Simple adding 1 (but why?} in A069659
may "save" A069659 as well.
Thanks, Zak
