Talk:Placid platypus function

Is this function known to be uncomputable?
Apparently vell has added to Template:Computational googologisms this function and Weary wombat function under the Uncomputable section. That made me wonder if these functions are actually known to be uncomputable. I haven't found anything answering this question online, but others might have some more luck finding this, or maybe proving it themselves. LittlePeng9 (talk) 13:05, September 20, 2015 (UTC)
