Raman almost certainly means "the special-q which lie in a range of 1.2 million". One prime in 33 is a reasonable figure for the density of special-q in a "typical" sieving region.

Ok, his statement wasn't precise but I think you should have been able to work out what he meant without any difficulty and could have been rather more polite in drawing his attention to the possibility of his statement misleading others.

Once again:

It is not the duty of a reader to "work out" what is meant.
When one makes a mathematical statement in a public forum, it is the
obligation of the author to clearly state what is meant.

There is a big difference between

1.2 million special q

and

special q in a range of length 1.2 million.

I assume that if one means the latter, then one will write the latter and
not the former. I assume that people mean what they say (or write).
To me, not to do so is disrespectful. It would mean that either the
person is too stupid to accurately convey his meaning *or* that he is
too lazy and sloppy to be bothered. Either assumption is an insult.

I disagree with you Bob. Raman's might not be fluent enough in English (if it isn't his native tongue). All of us have seen bad translations, some of them quite humorous. It is possible (I don't know if he is fluent in English or what his native tongue is) that it makes sense to him when he translates back into his native tongue, but doesn't make sense to us.

Also, this is a public forum of which math is only one part of, not a journal subject to peer review or a private math forum. IMO, the proper response would have been to ask Raman to clarify his statement because it was confusing. Instead you immediately attack him as a crank. Granted there are some people on this forum who write rather incredulous or just plain stupid things on a frequent basis. I'm certain that they rank high on your crank-o-meter. I haven't put Raman is in that category.

I assume that you weren't the victim of many months of daily mail bombs
from Raman; hundreds of junk mails per day containing total gibberish.....

Have you read his prior efforts on this forum??????

Very nice.

I have started the linear algebra for 2,836+. The matrix has
7.4M columns and should take about 39 days. I am using the CWI
solver which is only single threaded and is slower than msieve even
when msieve only uses a single thread. The matrix barely fits
on my 2Gb machine.

I have also started sieving for 7,277+. I will almost certainly need
someone else to do its LA. I simply don't have a machine that I
can use that has enough memory.

It seems likely that I will be able to provide.

11,244+ is complete. Per request, the log is attached rather than placed in code tags.

You gotta think green!

Congratulations!
