Multiple births come from two sources. First, sometimes more than one egg is released in a single cycle. If multiple eggs are fertilized, fraternal twins (or triplets or whatever) result. That's why you get so many multiple births with fertility drugs--they often force many eggs to be released at once to improve the odds, or implant multiple fertilized eggs in the hope that at least one will live.

Identical twins and triplets are grown from a single egg and a very energetic sperm, which strikes the egg so hard that it tears apart into two or three fragments, each of which becomes a baby. These babies all came from the same egg/sperm combo so they have the same genetic information. That's also why you don't see identical siblings more than triplets. There's only so many pieces you can tear an egg into with one impact.

Incidentally, conjoined twins also come from a sperm tearing the egg apart. If it doesn't quite separate, the pieces of the egg will form into two babies who are attached where the egg didn't tear.

i assume you mean she had thee sets of twins but were all born on the same day, she had 3 eggs ovulate and get fertilized at the same time then each egg split twice which resulted in 6 siblings with 3 sets of identical twins
