Ah, I see - you are allowing cuts to cut-off pieces. My apologies: I
defined a different sequence. (It's still a nice one, though :-) .)

By starting rectangle I meant the shape we start with, which in your
formulation is a square but which we might generalise to a rectangle
which is not necessarily a square. Unfortunately I was mistaken here too
because as Jack rightly points out the side length ratio doesn't affect
a(n). (Many thanks for this, Jack.)
