Are these "all the paths that are a single step", or do they include multi-step paths? Full connectivity is to be assumed?

Francesco, please don't edit your posts so as to destroy them and make people's answers meaningless and confusing. They may elect not to help you in the future if you do that.

[X, Y] = ndgrid(1:N);
identifiers = arrayfun(@(X,Y) sprintf('%d_%d', X, Y), X, Y, 'Uniform', 0);
Now just remove the diagonal ones and reshape into whatever order you want.
I do not understand how you want the distance to fit into this, or why you want to generate these identifiers.
