Best Answer

That's a series of 21 repetitions of the digit '9'. It looks like your cat got up on the table,

walked over to the keyboard, and stepped on the '9' key for a few seconds.

If this were an actual number, it could be more neatly expressed as [ 1021 - 1 ] . It has no

readily apparent mathematical or physical significance.
