Hello SeqFans,
Numbers showing, for any of their digit "d", exactly d copies of "d":

S=1,22,122,212,221,1333,3133,3313,3331,14444,41444,44144,44414,44441,...

Example:
312332 belongs to S as there are exactly 
one "1", two "2" and three "3" in 312332.

The sequence is finite (how many 
terms?) and the last term is, of course, 
this message header.

Best,
É.
