Strange history
 
One of our exponents has a history I can't believe.

If sirlpr really hadn't found a factor up to 2^69 in november, why all the computations later in december? I guess that's a typo in line number 4. Shouldn't it read

History no factor to 2^62 by "sirlpr" on 2008-11-08 ?

For a brief period the v5 server was not parsing results from v24 clinets correctly. sirlpr probably used a v24 client to TF from the start to 2^69 but the server only recognized the last bit level. Alternatively, sirlpr is a fiend who trial factors out of order to confuse people :devil:
