[Remind-Fans] complex rules in remind

[nx]

I'm having trouble working out how to describe the following scenario to remind:

# DAYS OFF WEEK 1: Sun,Wed,Thur
# DAYS OFF WEEK 2: Sun,Fri,Sat
# DAYS OFF WEEK 3: Sun,Mon,Tue

Then back to Week 1.

Anyone know how I can express something like this in remind?
