I get the same as Keith..
Diving boldly into the code for "geng", what happens is that when
n=29, main() calls "spaextend" and this function simply finishes
without calling itself (or anything else) any more times... inside
spaextend there is a conditiion
for (ixx =0; ixx < xlim; ++ix) {
.. recursive calls to spaextend
}
but at this point xlim = 0 and so there is no recursion..
When n=28, the function "genextend" is called instead which works
fine...
