MMM+Portable Hole+Drawmij's Instant Summons = ?

[Tahujdt]

I read an interesting theory where you cast DIJ on the portable hole, and then climb into the hole. You then cast Mordenkainen's Magnificent Mansion inside the hole. Once inside the Mansion, you invoke the summons to pull the hole containing the mansion into the mansion.
Three questions:
1) What happens when you unfold the hole inside the mansion and go inside and go through the mansion door again?
2)What happens when the spell expires?
2a) Can you cast permanency on a MMM?
3) how would you get back to the PMP?

1) you find yourself looking at the hole you just jumped into. It's a dimensional loop now.


2) DM fiat. There's no RAW concerning what happens to the occupants or unattended objects inside the MMM when it's duration elapses.

2a) no, but mage's private sanctum is on the permanency list.

3) Planeshift.

You may want to ask them here (http://www.giantitp.com/forums/showthread.php?t=272393). Good thread about planar (and dimensional) mechanics.

Huzzah!
I'm am now imagining the fantasy equivilant of the Infinite Improbability Drive bit from THGTTG, when Arthur and Ford get picked up.

When you summon the hole while in the mansion, you fail to get the hole. Instead you get a bowl of petunias, with a note scrawled in perfect script saying "404 error, your item cannot be retrieved".

Now there are inevitable seeking to kill you, have fun.

2a) no, it's not permitted.

operating on the assumption of 1) yes, you have a loop, there's no problem here, 2) is just as ill-defined as what usually happens to the contents of a magnificent mansion when the duration expires. if we rule that everything gets expelled, then you're now in your portable hole with your closed portable hole. you could open your portable hole either way, and then you still have a loop.

you could plane shift leave. if you don't bring the folded entrance to the portable hole, the portable hole is going to need to be garbage-collected at some point.

hope you don't have a refcount gc.
