Grotrian diagram of Hydrogen

Main Question or Discussion Point

Why is it that in Grotrian diagram only the 4p->3s is not allowed, but the 4s->3p, 4p-> 3d and 4d-> 3p are allowed ? I'm following the rules of Δl=±1 and Δm=0,±1 and they give the same numbers. I also tried with Δj=0,±1 and still the same.

The diagram is in error. The 4p->3s is allowed and should be present.

Both my physics books and the ones I've seen on the internet have it like this though
