Lanthanum flint - that’s what was meant in the description. Now I can talk about the ceaseless argument about the placement of the f-block amongst its neighbouring blocks: what are the two next members of group 3? La/Ac, Lu/Lr or nothing? The IUPAC is somewhat stupid in this regard and goes for the third option; Wikipedia and the members of its E-team (WikiProject Elements, of which I am a part) say the second, fitting with orbital considerations.
