I'll look into megarange casette.
You must be counting from the spokes and out. Most would consider the smallest sprocket, closest to the end of the axle, farthest from the spokes, to be the no 1 sprocket.
The innermost sprocket being significantly bigger is a megarange cassette, a fairly clever compromise between overall range, and close ratios. You get one bail out gear, and nice, rider friendly ratios for the most of your riding.
