Great to see interest in my old work .

The .gif images in http://cosy.com/cosylogo.htm of the paper I wrote
for the APL79 poster session are really my only "spare copies" of the
original .

The word CoSyLogo generates paths around 6 cubes viewing their main
diagonal and a point specified in its Right Argument .
an example with a random argument is on the F8 command list .

The essential algorithm is in the function EULER . I believe it could be
put into closed form , in an APL level notation , by someone who understood
transitive closure of boolean matrices better than I do - which ain`t much .

A major motivation for solving these problems in the first place was to
solve something which was virtually impossible to think about in any lesser
language than APL .

Understand the APL ( it`s well factored , and you can interactively decompose
it and step thru it in CoSy ) , and decide for yourself whether it is worth
exploding into one of the primitive languages .


Thank you again for your interest . If you have any problems or questions ,

"There is much to suggest that we have in fact become more tolerant
toward particular abuses and much more indifferent to inequalities in
individual cases, since we have fixed our eyes on an entirely
different system in which the state will set everything right. It may
even be ... that the passion for collective action is a way in which
we now without compunction collectively indulge in that selfishness
which as individuals we had learned a little to restrain ."
