What number can be expressed as sum of 6 squares
What is the smallest number that can be expressed as a sum of six different squares but cannot be expressed as the sum of five different square numbers?
1^2 + 2^2 + 3^2 + 4^2 + 5^2 + 6^2 = 91
Could you express 91 as a sum of five different square numbers?
