In http://plato.stanford.edu/entries/wittgenstein-mathematics/ there is no
reference to 770 but to 777. Also, in Victor Rodych's
"Wittgenstein on Irrationals and Algorithmic Decidability"
(see http://www.springerlink.com/content/u54u44430088641t/) there is no
reference to 770 but only to 777. And these are just two sources that discuss
this ``problem.''
