Tom,

check the igraph package. Although structural balance is not implemented, for three or four nodes it might be straightforward to do a quick implemntation which works for small graphs.

Btw. what is exactly you want to do? List the number of balanced and unbalanced triangles? Ot the triangles themselves? What is a semi-cycle? Could you point me to a good online reference about structureal balance?

Thanks,
Gabor
