I usually just write the number sequence in my phone/digital notes, for example " 1 > 52 > 23 > 53 " and mark them done like " 1(done) > 52(done) > 23 > 53 "
They are like cheat codes for reality. Numerology in truth, is one of the most important factor in manifesting a working. If you use the perfect numbers for a certain thing, the numbers that's meant to be used for that and represents that, it is guaranteed to manifest.
Planetary squares work like this, the numbers make a perfect structure trough which things related to that planet's energy can manifest.
Although it depends on what you want to achieve with them, we can say the effects are "permanent" or "absolute", meaning that if you want to change something with it, it is going to stay changed as long as you change it again, or if you want to manifest something, it is going to manifest.
But common sense and good practices related to manifestation workings apply to them as well. If you have a specific use case you want to use a square for, tell us and we can help understand how it will manifest.
