The response selfie-gek got says “Each calculation starting from your origin equals PRIME” and “MAIN FAM ID: 3\_141\_541”… Does this mean the origin is 3141541? (which is not a prime, btw, and neither is 141). Are we supposed to calculate something with 3141541 as one of the values? How is every hint more confusing than the last??

I tried to derive a prime from Fe2O3 and landed on just using O3

Wonder if we should have a separate topic to list all the occupied windows?

Window? Like in a tower. I just requested 31, see how it goes

Okay, I have a confirmed window now too 🙂
Are we going on a cruise or getting apartments with outward facing windows?!

my prime is [REDACTED]

It most certainly is, I could pick a lot of points of origin for my Journey
as a Traveller, a WT Investigator and a PSS Operator and a long standing
Keeper of the Trace, but this was the first thing I entered into Calculator
when the module appeared yesterday, and I enjoyed seeing it be displayed as
a Prime Number.
Don't you agree it is a fitting choice?
```
System

Thanks for keeping the TRACE.
Your window is 4013.
You will have a nice point of view.

Thank you system, I look forward to the sights <3

I wonder if anyone has tried to cheat, asking for a window that is not actually prime?

If you exist in 4d space as a trajectory, your origin could be 0? Which is not a prime.

Yes, seems so, and the calculators purpose is to help you find a prime number, since it always lands on the nearest one no matter your input.
Then just submit it to system. If it isn’t taken, you’ll get a window. If it is, I think they’ll let you know to try another.
so maybe you can add or subtract or multiply a series of numbers that mean something to you personally, and see what the nearest prime number to it is that propogates, and choose that as your Operator ID
you can see some of the ones chosen already here
