Thanks. I was basically looking for confirmation that I hadn't overlooked something in the documentation. The transposition of the first two dimensions, compared to their interpretation in Plot3D, is something that I think ought to be mentioned explicitly as the second item in the Details section of the documentation, imediately after
In ListPlot3D[array], array must be a rectangular array. Each element can be either a single real number representing a z value, or an {x,y,z} triple.
