Three codes with 16 characters each of which one doesn’t have any numbers. The other two contain a total of 16 numbers. A few things we can already figure out.
1- The three codes must be combined in some way
2- One of the keyword must contain one number. A good candidate is 3rdlaw
After putting all the three codes together and using rectangle no rearrange would work. A skip of 3 gave sitrep at the end of the string. This seems to indicate the right path but the order is wrong. Let’s make one long string using this order: code 1, code 3, code 2
msfqjtcjj2548293sinirdtsirlaedepw725939276rakqkr
Use a skip of 3
mqc283ndiae792rqsjj52sitrep237akftj49irsldw596kr
We can now see sitrep right in the middle of the string
Split in groups of 16 characters
mqc283ndiae792rq
sjj52sitrep237ak
ftj49irsldw596kr
The second row is a valid passcode
sjj52sitrep237ak
Take the first and third string
mqc283ndiae792rq
ftj49irsldw596kr
Read the codes alternating letters between the two strings
mtc48inside596rr
fqj293rdlaw792kq
We now have all three passcodes
sjj52sitrep237ak
mtc48inside596rr
fqj293rdlaw792kq
