5040^49 can be added to the list here. The C181 has been ECM'd to t45.

I was able to split all of the others on new base 5040.

A couple of questions to keep my spreadsheet current:

Are all of the C153s now ECM'd to t50?

Have all of the ones that were added from new bases 47616, 1305184, and 1727636 been ECM'd to t50?

47616^36 can be added.

It was ECM'd to t45.

I worked all of the untouched exponents on the 3 recent new bases. This is the only one that still remains at index 1.

Can you be more specific?:

1. Did you ECM the entire list to t45 with the exception of the two at the end, i.e. 95^94 and 86^99?

2. Where have you started t50 from? Did you do 95^94 and 86^99...
