The codimension 3 bifurcations associated with a heteroclinic loop formed with two saddle-foci (one has a pair of image eigenvalues) and two of their heteroclinic orbits are considered in the 3-dimensional space.It is proved that,in a neighborhood of the heteroclinic loop,there are countably infinite 1-homoclinic orbits and l-heteroclinic orbits.Meanwhile,under a transversal condition,the existence of infinitely many heterclinic orbits joining two saddle-foci.1-and 3/2-heterclinic loops connecting a sddle-focus and a limit cycle produced from Hopf bifurcation,and 1-homoclinic orbits approaching the limit cycle or a sddle-focus are obtained,and the bifurcation surfaces and the existence regions are also given.
