Putting the words nmode and assertion into the search engine of the amber
mailing list archive (http://amber.ch.ic.ac.uk/archive/) yields a number of
useful hits. For example: http://amber.ch.ic.ac.uk/archive/200409/0115.html

In your case you need a total of 409700851 + 46084583 = 455785434 words =
3477.37 MB of memory. So you need to be able to allocate at least this much
memory on your machine. In reality you will need quite a bit more for other
parts of the program, operating system overhead etc.

All the best
Ross
