Line 23:

in a fixed, finite virtual volume without hard boundary.

The absolute sizes of the particles were increasing but particle-to-particle relative sizes remained constant.

In general, the LSA can handle

combined with a present or

absent hard boundary.

In a final, compressed, or "jammed" state,

some particles, the so-called "rattlers," are not jammed, they are able to move

for spherical particles, though the spheres may be

of different sizes

Any deviation from the spherical

(or circular in two dimensions) shape, even a simplest one, when spheres are replaced with ellipsoids (or ellipses in two dimensions)
