COMMENTS
The sequence is well-defined, in that a(n) exists for all n>=0. For the reasoning see A078134.
FORMULA
a(n)=min( m | A078134(j)>n for all j>m).
EXAMPLE
a(0)=23, since numbers >23 can be written as sum of squares >1.
a(2)=39, since there are at least three ways, to write a number >39 as a sum of squares >1.
