filter-list. For numeric groups (integers, reals, points, and vectors), you can specify other relations by including a special -4 group code that specifies a relational operator. The value of a -4 group is a string indicating the test operator to be applied to the next group in the filter-list.
Unless otherwise specified, an equivalency is implied for each item in theThe following selects all circles with a radius (group code 40) greater than or equal to 2.0:
(ssget "X" '((0 . "CIRCLE") (-4 . ">=") (40 . 2.0)))
The possible relational operators are shown in the following table:

The use of relational operators depends on the kind of group you are testing:
