I have done the first ten listed with syntheses greater than or equal to one glider per bit that appear on mniemiec's website. ... Anybody want to help...

This is probably the next best step, as far as the still-lifes are concerned. As of yesterday, I had 19 remaining 15-bit still-lifes at 1 glider per bit, and 94 at greater than 1 glider per bit. This does not yet include Bob Shemyakin's work at completing the synthesis of the remaining 15-bit still-lifes. (I still need to assimilate those, and see if any alternate synthesis paths might be more optimal, especially in light of some of the new converters that have been discovered in the past year).

All but one of the above syntheses (#4) improve the state of the art. Congratulations! 6 of them can be slightly improved, by tightening up initial still-life synthesis and/or final cleanup:

#1 (15.5): Reduced from 13 to 12 (row 1 left).

#3 (15.38): Reduced from 12 to 11 (row 2 left).

#4 (15.45): Reduced from 14 to 11 (row 3 left). However, this is obsolete; you had previously built this from 12 gliders on 2016-10-14; BlinkerSpawn had reduced it to 11, and I had reduced it to 10. (row 4 left).

#6 (15.79): Reduced from 10 to 9 (row 1 right).

#7 (15.80): Reduced from 13 to 12 (row 2 right).

#8 (15.92): Reduced from 13 to 12 (row 3 right).
