Can anyone help me make sense of a ferrite core datasheet?

I need help understanding a datasheet for some ferrite cores I bought to wind transformers on.  This is the datasheet:  The main thing I need to know is the inductance per turn of wire on the core so I can design the transformers to minimize inductive reactance and such.

That's what  AL is for.

Inductance = AL x n2

You need to know cross sections etc for winding sizes and power ratings, but the fundamental thing is the AL

Inductance is in nH, n is the number of turns.
