COMMENTS

Numbers n with property that they can be written as n = a^b*c^d*e^f*... and if all the multiplication and exponentiation signs are deleted then abcdef... is the same decimal number. The final multiplicand in the product, uniquely, may or may not include an explicit exponent.

It is not clear from the link whether there may be other printer's errors in between the listed terms. The linked page says merely "Here is a list of all the known printer's errors in base 10 with fewer than 100 digits".
