I can confirm the OP is correct, the part does not exist. It was originally listed
in 75826 but there was a inventory change that went through on 3/5/17. That was
the only set that piece came in (but not really). I have all 6x6 not the 8x8.
Found this out after someone ordered it from me a few months back.

Must have been incorrectly inventoried now corrected, it is 6x6x3 part #50747
From 75826 king pig castle there are 50 sellers with wrong part
Don’t know how y’all correct this, so just FYI
Thanks - it's not something we fix unless we are 100% sure that all the sellers
have the wrong parts.
I will contact some of the sellers to double check and take it from there...

We really don't do anything. It is up to each seller to correctly verify
their inventory when parting out sets. The set inventories are to be used with
the caveat that they may not be 100% correct. In fact, each inventory has a disclaimer
at the bottom of the page that states "BrickLink does not guarantee an inventory
to be correct and therefore an inventory should be only used as a guide."
