4 4s puzzle

i have greatly enjoyed working out this puzzle for myself
the people on this site have gone to a lot of work to solve it

is there a site anywhere for the similar puzzles 5 5s or 3 3s
i have searched but i cannot find one

The main issue that I see with that site is, they don't require the use of all 4 of the 4's. This ups the challenge.

we could make our own list if people want

I started this same puzzle a year ago at:

Also in 2005 by someone else at

And a related 4-9's puzzle at:

There are several links in these posts to other web sites that solve problems with 4 of just about anything and just about any set of rules you like.
