Sum of how many squares of successive positive integers is a square number?

Surprisingly enough, trivial answer discounted, only one number qualifies!

Sorry, my wording fooled you - my fault.

For you to continue    ==>   1  (s=1) and 2 (s=9+16) should be considered trivial -  there is one  additional  2-digit answer and  it can be shown there are no additional possibilities.

So, as they say in the Navy - carry on, Steve!
