The website http://www.trnicely.net/gaps/gaplist.html contains a long list of maximal and nonmaximal prime gaps. In this list, the largest maximal prime gap is one of length 1476:
Gap Start: 1425172824437699411
1476* CFC TOeSilva 2009 35.31 19 1425172824437699411
My question is if there are more updated lists of maximal prime gaps (with larger maximal prime gaps). If this is the case, I would like to know reliable sources for those lists.
