777 is also part of that phenomena and as we have already seen, the number 11 was key to the September 11th attacks on the World Trade Centre.

Don't forget about the London bombings which occured on the 7th day of the 7th month in 2005, which is 2+0+0+5 equals 7.
All that together makes 777. There were also 7 explosions in total on that day.
