Four rows, each holding one point or two, describe a geomantic figure completely. Everything else is interpretation laid over that.
The pattern
Acquisitio is double, single, double, single, reading Fire, Air, Water and Earth from the top down, six points in all. It is one of the two figures in the set whose rows alternate, heavy and light in strict turn.
Flipping every row
Change each row from single to double and from double to single and Acquisitio becomes Amissio, the other alternating figure. Gain and loss are therefore partners under the operation, and the two are the only figures whose rows never repeat a state twice in succession.
Why the alternation matters
Because the rows alternate, both figures place an active and a passive element next to each other at every step, reading Fire against Air and Water against Earth. Handbooks that reason from the elements make something of this; handbooks that reason from the Latin names largely do not, and the atlas records the structure rather than adjudicating between them.
The attributions are a separate layer
The atlas records a planet, a sign and an element for this figure. Those were attached by the astrological tradition and the Latin sources do not agree in every case, so they are recorded as a tradition with variants. The point pattern above is intrinsic: anyone who draws the figure can count it, and it is the same in every source from the Arabic tradition onward.
