How to write a regular expression to select every fourth coordinate?

Question

Regular Expressions

Given the coordinates of the city:

[65.051193, 35.314801] [65.127703, 35.29793], [65.184477, 35.346113] [65.220663, 35.435205] [65.252509, 35.612738] [65.278715, 35.955825] [65.278063, 36.031102] [65.267529, 36.100086] [65.244672 , 36.165725] [65.250549, 36.279774] [65.241681, 36.358604] [65.216342, 36.43206], [65.181336, 36.473356] [65.139086, 36.476838] [65.103086, 36.438112] [65.065371, 36.318248] [65.052352, 36.229193 ] [64.97854, 36.2276] [64.933542, 36.170912] [64.914537, 36.103882] [64.90965, 35.982465] [64.877042, 35.851886] [64.867921, 35.778449] [64.837907, 35.806084] [64.803037, 35.806064] [64.771271, 35.775214] [64.746388, 35.716157] [64.757677, 35.673386] [64.836913, 35.634839] [65.011804, 35.469228] [63.580076, 35.897179] [63.626957, 36.456205] [63.748226, 36.590402] [63.956503 , 36.555591], [64.278274, 36.877611], [64.316933, 37.015157],[64.625588, 36.568498], etc.

We will assume that the record of the form - "[64.316933, 37.015157]," is one coordinate. You must use the regular expression to identify and remove every fourth coordinate

Example:
[65.051193, 35.314801] [65.127703, 35.29793] [65.184477, 35.346113] [65.220663, 35.435205] [65.252509, 35.612738] [65.278715, 35.955825], [ 65.278063, 36.031102] [65.267529, 36.100086] [65.244672, 36.165725] [65.250549, 36.279774] [65.241681, 36.358604] [65.216342, 36.43206] [65.181336, 36.473356] ... In the end, all that is inside tags should be highlighted and removed. The task is complicated by the fact that all coordinates are of the same type. Please let me know if there is a possible solution for this problem.

Skip three repetitions of closing brackets with a semicolon, capture the next brackets.
