i'm confused... you said if you could somehow get the cube to have an odd number of layers, the center would NOT be fixed... all of the above puzzles have an odd number of layers and the centers ARE fixed
and how exactly are you defining the "layers", because the pictures i am looking at right now, only show that the gigaminx has one layer more than the megaminx and the teraminx has only one extra layer than the gigaminx... and to clerify that is per turn-able face...

Hopefully this will explain it a bit better.
On a 3x3 cube, (without moving the core) there is 1 turnable layer on each side, just like a megaminx.
On a 5x5 cube, (without moving the core) there are 2 turnable layers on each side, just like a gigaminx.
On a 4x4 cube, (without moving the core) there are 2 turnable layers on each side as on a 5x5 cube, but there are no fixed centers. This is because there is no middle layer on a 4x4 cube.
Therefore, a 4x4 megaminx should have 2 layers, but no fixed centers, as the one posted here: http://www.twistypuzzles.com/forum/viewtopic.php?p=96714#p96714

The megaminx has a centre and 2 additional layers, making it a 3x3 equivalent.
The 4x4 rubik's cube has 4 centres on each face, and 2 additional layers.
The 2x2 cube has no centres, only 2 "additional " layers, formed by corners
Looking at the pyraminx crystal, a face is made of 5 corners and 5 edges and no centres, so it is a 2x2 like puzzle. Look at it this way, if the pyraminx crystal would be a 4x4, then what would the 2x2 pyraminx crystal look like? You cannot have less than 0 centres, so there is no such thing.
However it is not the 2x2 of a megaminx, since the actual 2x2x2 cube has no edges, only corners, but the pyraminx crystal does have edges.
This is why the impossiball is the only 2x2 version of the megaminx (together with kilominx), because it has no edges either.

again.. let me point out that you are ALL looking at the anatomy of the puzzle... not how the puzzle must be solved... there is no 4x4 version of the megaminx in production today... therefore, thinking in terms of how the puzzle must be solved, the pyraminx crystal is the closest thing to a 4x4 version in the minx family, simply because there are no fixed centers to build on but the puzzle still has edge pieces...
that being said, the pyraminx is no where near as close to being a 2x2 minx as the kilo... as with a 4x4, if you simply turn either BOTH the right, left, upper or down layers, you come up with a 2x2 puzzle... the same thing can be done with a praminx crystal...

No, you are looking at it all wrong. The pyraminx crystal is simply a megaminx variant made by extending certain pieces to hide the center. Just because it doesn't have a fixed center makes it a 4x4 in the same way the link I posted a bit back is a 4x4. The number of layers on a pyraminx crystal makes it equivalent to a deeper cut 3x3, which is all it is. A gigaminx or even a megaminx should be considered much closer to a 4x4.

I have one of these.. Once I lubed it and loosened some screws it turns very well

see in the attached picture of a theoretical 4x4minx, how there are more layers. 4 of them, and the centres could be misplaced by assembling them in different places etc, so they're not fixed, just like a 4x4.
on a pyraminx crystal you can't do that, and it only has 3 parts to an 'edge' 2 corners and an edge. like a 3x3?
pictures are fun

good thing it doesn't exist
my point exactly... if i had to pick one out of all the minx family to compare to a 4x4 (that currently exists), it would be the pyraminx crystal, because no one side has to be that color... i don't know if that makes any sense to you guys... i guess i'm just thinking outside the cube...
and to Felipe... from the research that i was able to do it looks like the Pyraminx crystal actually has the same core as a Megaminx, it's just that the body of the puzzle has been built "above" it... like my 4x4, if you take it apart, the core is exactly that of a 3x3...
that picture makes me sick to my stomach... made me remember how long it took me to memorize the parity alg for the 4x4 and 5x5 cubes
but i would love the challenge... i think i will draw up a color version of that and post it... might be fun

Parity also doesn't exist on a 4x4 minx or the pyraminx crystal. Your point is nulled.
i think we just came to the conclusion that there is no such thing as a 4x4 minx, so please try to keep up with the topic before you comment...

No, you were trying to compare the two by saying that since OLL parity doesn't exist on odd minxes, PLL parity must still exist on even minxes because of the lack of a fixed center, and I assumed you were comparing that to the pyracrystal somehow.
Maybe I'm just giving you too much credit.

again, thinking in terms of the puzzle's anatomy, that would be true...
but the simple fact that each side does not have a fixed center makes it, in my personal opinion, the equivalent to the 4x4 Revenge.... i say this because even with a 4x4 Revenge, you still solve it the same way as a 3x3, but not after building the centers, then pairing the edges... just with the Pyra Crystal, you can skip the step of edge pairing... sounds like so much fun to solve
you must not have seen this, but the parity errors would be included in that comment...
i think i've created a working model of what a true 4x4 minx would look like... just not sure if i want to post it here... from what i've seen, it has never been created before... certainly would be worth it to try to get patents for it first...

Maybe, but do you realize how much a patent costs and how long that would take? Look at the kilominx, is there a patent on that? No. Gigaminx? Teraminx? Petaminx? No. Unless you were to get it massed produced, it (most likely) would not be worth your while.
By the way, there is no parity on any minx, even or odd (it just looks like there is).

LOLOLOL
1. The pyracrystal has no parity
2. You don't have a working model for a 4x4 minx
