100 is a square which is also a sum of 4 consecutive cubes.
Are there any others?

xdog,
Evaluating:
(2x+3) = a^2 and (x^2+3x+6) = 2b^2 for x=0: a=b=3^(1/2)
(and c=2*3^(1/2), so 2c^2  15 = 9)
(2x+3) = a^2 and (x^2+3x+6) = 2b^2 for x=1: a=b=5^(1/2)
(and c=2*5^(1/2)), so 2c^215 = 25)
it seems it can't be assumed that a,b,c, are integers.
