|There are 1250 XYYXF
composites from C154 to C321 by this time. Currently 8 of them are
the remaining 1242 are available for
Blinking squares mark reserved composites. The color depends on the decimal length of the composite; that's shown on this chart representing the distribution of the composites by their decimal length:
You see, there's a lot of work to do. It would be fine if you choose some of these squares and cause me to add a few lines to the table below.
To choose the most efficient method of factorization and to avoid wasting CPU time, please take into account that all the composites passed P±1 tests with B1 from 100M to 4G and ECM tests up to B1 = 11M, and now are being tested with ECM at B1 = 43M by yoyo@home.
Some of the numbers survived deeper ECM tests; this table shows the amount of that additional work.
