types of barrier options

This article states that there are 16 types of barrier options but shows 8 in the table

What are the other 8? Thanks

European/American => 8 * 2 = 16 ?

Nope.

Knock-In/Knock-Out

Also there are not only plain vanilla options, thus might be some kind of exotic options (e.g. Bermudan).

who cares ! we are on the verge of getting the results… take a token and get in line with your options !
