Help settle a debate! How often has a conjunction of Regulus, the Moon, Jupiter, and Mars to within a 5 degree orb occurred over the last 5000 years?

ChatGPT says that it’s actually rather difficult to calculate but estimates it has happened 10-30 times. I’m hazarding a guess that while basically rare, it has probably happened at least, let’s say, a half dozen times over the last 5000 years.

Bonus points if you can predict with high confidence specifically how often this alignment can be expected to happen over the Sphinx in Egypt just before dawn!
