[Jprogramming] 11:11:11 repunits

[John Baker]

Today's date 11:11:11 is generating some interesting internet items. I saw
a cute blog posting about "repunits"

http://mathlesstraveled.com/2011/11/11/fun-with-repunit-divisors/

The following j expressions generate the table shown in the blog posting.
 I couldn't come up with anything more elegant.

repunits=. 'x' ,~&.> (2 + i. 19) #&.> '1'
repunits ,. q:@". &.> repunits
