Dear Dr Fiedorowicz
Re: http://www.math.ohio-state.edu/~fiedorow/math655/Peano.gif
I am writing to you on behalf of the Wikipedia project
http://www.wikipedia.org, an endeavour to build a
fully-fledged multilingual encyclopaedia in an
entirely open manner, to ask for permission to use
your copyrighted material.
Your website has a page on the Peano curve that has a
wonderful illustration showing the first six
iterations which would undoubtedly enhance our page
http://wiki.riteme.site/wiki/Space-filling_curve
I should like to ask for your permission to use it
under the terms of Wikipedia's licence.
Wikipedia licenses all its content under the licence
developed for purposes of free documentation by the
Free Software Foundation, the text of which can be
found at http://www.gnu.org/copyleft/fdl.html It
should be borne in mind that if you choose to allow
Wikipedia to use the diagram, it will remain
copyrighted to you; however, the said licence
stipulates that third parties must be permitted to
reuse the licensed work so long that they retain the
licence of this work and any derivatives from it.
Consequently, you may wish to consider carefully
whether you are prepared to compromise some of your
rights granted to you by copyright law by licensing
your work as suggested. If you do choose to give
permission we shall greatly appreciate it.
Thank you for your time and consideration.
I look forward to your reply.
Yours faithfully
Theresa Knott
