hello we all are familiar with Ramanujan's number 1729 i thought of every one recognizing a special number well thought of mine ....65...
.what so special about it (maybe not so special
)
it is smallest number to be expressed as sum of squares of two distinct pairs of numbers (i am not sure although!!) \(\displaystyle 1^2+8^2 = 4^2+7^2 \)
