Let the diophantine equation $ \frac{1}{x} + \frac{1}{y} = \frac{1}{n} $ with $x \le y$
How many solutions are there for $ n=1000000! $ ?
As the answer is a BIG number, use the following condensed representation:
(First 10 digits)[(number of remaining digits](Last 10 digits]
For instance, for 2^127, the representation is: 1701411834[19]5884105728
Example: $ 8583170787[2]5400804688 \textrm{ for } n = 100!$
