Can anyone confirm that these two sequences are the same? A140612 is
"Positive integers k such that both k and k+1 are the sum of 2 squares",
and A160053 is "Numbers k with property that k*(k+1)/2 is sum of two
nonnegative squares". As far as I checked, they seem to be equal, but there
are no xrefs.
