Happy New Leap Year
2012 is a leap year, i.e. it has 366 days. 366 can be written as the sum of consecutive square numbers:
366 = 82 + 92 + 102 + 112
Non-leap years have 365 days. 365 can be written as the sum of consecutive squares in two different ways:
365 = 102 + 112 + 122
365 = 132 + 142
Neither 366 nor 365 are square numbers themselves. Are there any square numbers that can be written as the sum of consecutive squares?
