primo primality certificates - (un)lucky numbers
 
Recently I certificated some prime numbers from [I]factordb[/I] database using [I]primo[/I] and observed big differences in time required to certificate. Below are my best / worst iterations so far:

[CODE][5]
Type=3
[COLOR=Lime]Gain=138[/COLOR]
Index=1.4
D=-4
H/G=1/1
[/CODE]Worst: N=[URL="http://factordb.com/index.php?id=1100000000294463118"]2^2841+435[/URL]
