The 4 ideas with the same theme [problem with defining a number with maximum words]:

Berry's Paradox considers the meaning of 'The least number not named by this name' [Bostock]
Berry's Paradox: we succeed in referring to a number, with a term which says we can't do that [Hart,WD]

'x is a natural number definable in less than 19 words' leads to contradiction [Priest,G]
