# Polymath8: Writing the paper

The main objectives of the polymath8 project, initiated back in June, were to understand the recent breakthrough paper of Zhang establishing an infinite number of prime gaps bounded by a fixed constant \$latex {H}&fg=000000\$, and then to lower that value of \$latex {H}&fg=000000\$ as much as possible. After a large number of refinements, optimisations, and other modifications to Zhang’s method, we have now lowered the value of \$latex {H}&fg=000000\$ from the initial value of \$latex {70,000,000}&fg=000000\$ down to (provisionally) \$latex {4,680}&fg=000000\$, as well as to the slightly worse value of \$latex {14,994}&fg=000000\$ if one wishes to avoid any reliance on the deep theorems of Deligne on the Weil conjectures.

As has often been the case with other polymath projects, the pace has settled down subtantially after the initial frenzy of activity; in particular, the values of \$latex {H}&fg=000000\$ (and other key parameters, such as \$latex {k_0}&fg=000000\$, \$latex {\varpi}&fg=000000\$…

“如果把我和同伴们所经历的教育过程喻为一次探险，我就是一个走到最后的幸存者。”

“我很羡慕城市的同学”

1988年，我出生于陕西平利县一座村庄。2007年，在县城中学复读一年后，我考进了华中科技大学。

2003年，我参加中考时全中学两个镇的学生只有6人考入县中，我当时考了第7，留在了八仙中学。而在2004年的中考里，全年级仅一人考入县中。
